Boris Johnson warned a coronavirus vaccine may never arrive and restrictions may have to remain in place for “the long haul” as he set out his limited relaxation of the lockdown.
In a 60-page document the prime minister set out detailed guidelines for the changes to apply from Wednesday – including advice on returning to work, outdoor exercise and picnicking in parks.
Businesses, unions and police had called for clarity on the easing of restrictions after his plan – first set out in a TV speech on Sunday night – was criticised as “vague” and “indecisive”.
Meanwhile the UK death toll rose by 210 – the lowest daily increase since late-March – to a total of 32,065.

Some UK pubs could open from July 4, says government
Some pubs could reopen as early as July if they can keep drinkers apart, Dominic Raab has said.
The tentative plan to allow cafes and restaurants to reopen in the third phase of the lockdown easing could also include pubs, the foreign secretary suggested for the first time.
Prime minister to give detailed plans on easing lockdown
Boris Johnson will provide more detailed plans to gradually ease the coronavirus lockdown when the government publishes its official guidance on Monday
The prime minister will also face MPs after offering his "first sketch of a road map" for restarting the economy and social lives in England.
He will give a statement to the Commons, with more information expected on a Covid-19 alert system, use of face coverings and the return of professional football.
Labour say Boris Johnson's statement lacks 'clarity and consensus'
Labour leader Sir Keir Starmer said the announcement lacked "clarity and consensus", while "effectively telling millions of people to go back to work tomorrow" without clear guidelines.
He said: "This statement raises as many questions as it answers, and we see the prospect of England, Scotland and Wales pulling in different directions."
How the papers reacted to PM's statement
Boris Johnson's announcement of a "road map" out of coronavirus lockdown is being dissected in the nation's papers on Monday.
The Daily Telegraph, which formerly carried a column from Mr Johnson, has printed an opinion piece suggesting this road map had "vague directions".
Camilla Tominey, the paper's associate editor, writes: "For nearly two months, we stayed indoors, did what we were told and hoped the end would soon be in sight.
"Yet, in a statement that left more questions than it answered - Boris Johnson last night offered the British public a slither of light at the end of the tunnel but no ETA."
The Sun's Trevor Kavanagh says Mr Johnson has been "paralysed by indecision, kicking himself for unforced errors, terrified of being blamed for every new death".
However, he suggests the "public sector 'blob"' has led Mr Johnson's thinking, citing its warnings of "mass fatalities if the Government makes one false step".
He adds: "Downing Street is now hostage to the health-and-safety mafia, whipped into line by opportunist public sector unions who have, to coin a phrase, taken back control."
Stephen Glover in the Daily Mail writes that Mr Johnson is walking a "tightrope" between business, members of the public who are urging reopening, and "trade unions, perhaps a majority of the public, the devolved administrations (notably the scheming Nicola Sturgeon in Scotland)".
In a piece headlined "It's hard to see what else he could have done", Mr Glover writes: "Those who want Britain to get back to work almost immediately will have been disappointed, while the cautious and nervy will be worried he is going too far too quickly, and jeopardising the progress that had been made.
"The question we should ponder is whether, if any of us were in Boris Johnson's shoes, we would act very differently. I don't think most of us would. Let's face it: he's walking a tightrope, and if he leans too far in one or other direction, he is liable to fall off."
An editorial in The Times says the prime minister was hoping to signal "a shift of emphasis, more than a radical change in the lockdown rules".
It said: "Though public support for lockdown has held up extremely well, adherence has frayed, with some police officers reporting that they were "fighting a losing battle" over the bank holiday weekend as parkgoers took advantage of the fine weather.
"That is a battle they can now leave behind them.
"The path back to normality still looks long and treacherous. Mr Johnson tried to offer hope that, with public co-operation, an exit is within sight. But he was also clear: there is no Plan B."
Meanwhile, Kevin Maguire in the Daily Mirror, says there is now "proof there is no crisis that Tory charlatan Boris Johnson can't make worse".
"Botching an easing of the lockdown was, I suppose, expected from an incompetent PM bungling the fight against the plague and lumbering Britain with Europe's highest official death count," he adds.
Labour calls for greater clarity on workers returning to jobs
Labour has called for greater clarity on how workers are meant to return to their jobs during the coronavirus crisis.
The party's shadow home secretary Nick Thomas-Symonds told BBC Radio 4's Today programme: "People should be able to work in safety.
"People shouldn't be in the uncertain position that they are today.
"Certainty helps workers. It helps employers. And, that's what the Government should actually be providing."
The comments follow an address to the nation on Sunday by prime minister Boris Johnson in which he said people who cannot work from home should be "actively encouraged" to return to their jobs from Monday.
Some pubs in England could open from 4 July at earliest, says Raab
Heathrow passenger numbers down 97%
Heathrow airport's passenger numbers were down 97 per cent year-on-year in April.
It said just 206,000 people travelled through the airport last month, which is "the same number it would typically serve in just one day".

Dominic Raab wrong to say individuals can meet two people at same time, government admits
People will only be allowed to meet one of their parents after the lockdown is eased, the government has said in an embarrassing U-turn.
Moments after Dominic Raab suggested it would be possible to meet two people in some circumstances – provided it was in a park, at two metres apart – the public has been told that advice was wrong.
The U-turn comes amid further confusion over the date when staff will be urged to go back to work if they can and whether some pubs could reopen from July.

Piers Morgan attacks Tory MP who gives confused advice over rules on visiting family
Piers Morgan attacked a Conservative MP for giving confused advice over the new lockdown rules on live television, the day after Boris Johnson gave an address laying out the government's plans, Rory Sullivan reports.
The Good Morning Britain host asked Andrew Bridgen, the Tory MP for North West Leicestershire, whether he can now visit his two sons who do not live in his household.
Mr Bridgen replied by saying he could visit them as long as he abided by social distancing.
The ITV presenter said Mr Bridgen's response was "completely against the new rules".
'Very serious concerns' about children returning to school in June
The general secretary of the teachers' union said the profession has "very serious concerns" about children returning to school on 1 June.
Patrick Roach, of NASUWT, told BBC Breakfast: "The fact of the matter is the Government has announced a date but hasn't come forward with a plan about how schools will ensure that they're safe for pupils and safe for staff to be in from June 1.
"And the prime minister said that it would be madness to risk a second spike in relation to transmission of the virus. Well the profession has got very serious concerns about that announcement of June 1, whether indeed it is possible to achieve it, but also how to achieve that in a way which is safe for pupils and staff."
He said there is strong evidence schools are lacking personal protective equipment (PPE), adding: "If you're dealing with five and six-year-olds and 11-year-olds, how to ensure stringent social distancing in that context is a big challenge and government simply haven't answered that challenge.
"And finally, just in terms of risk assessments, parents will want to know that schools are going to be hygienic, they're going to be safe for their children to be in. And we still don't have any clear standards about what safe cleaning routines would be like within a school context and we need to have that."
Government's decision to loosen lockdown rules questioned by British Medical Association
The chairman of the British Medical Association (BMA) has said he does not know on "what basis" the government has made the decision to loosen lockdown rules and change the message from "stay at home" to "stay alert".
Dr Chaand Nagpaul told BBC Breakfast: "I'm not sure on what basis the government has made this decision in England. And remember, we should only ease the lockdown when, first of all, we feel it's safe to do so.
"At the moment we have more people dying on Saturday than we had at the beginning of the lockdown.
"We've also seen about 4,000 new cases every day over the weekend, and that's just a fraction of the real number of new cases because of the limited testing so there's a considerable amount of community circulation of the virus going on.
"And if we now allow the public to go to local parks in an unlimited sense, and to go outdoors... what we've not heard is how the Government will enforce social distancing and how it will avoid a whole neighbourhood playing in a park, with footballs moving from one group to another, and spreading the disease.
"So, I'm really concerned that there is no clarity.
"And as regards people getting back to work - millions of workers in construction and manufacturing -there's no information of how, practically, we will be able to ensure social distancing."
'This is shambolic', Ed Miliband says
After Dominic Raab indicated people would not be expected to go back to work until Wednesday, shadow business secretary Ed Miliband tweeted: "The PM didn't say workplace changes applied from Wednesday.
"He said 'And the first step is a change of emphasis that we hope that people will act on this week.' Wednesday was only mentioned in relation to other changes.
"Words matter. Clarity is essential. This is shambolic."

Revealed: Fire services 'dangerously underprepared' for coronavirus pandemic, documents show
Fire and rescue services had not been given government guidance on reacting to a UK pandemic for 12 years before the coronavirus outbreak, documents have shown, our home affairs correspondent Lizzie Dearden reports.
The Fire Brigades Union (FBU) accused ministers of leaving firefighters “dangerously underprepared” and ignored repeated warnings through a decade of austerity.
Downing Street and government ministers have repeatedly claimed that the UK was “fully prepared” for a new outbreak, but evidence seen by The Independent calls that into question.
Philippines infections pass 11,000
The Philippines' coronavirus infections have broken past the 11,000 mark, the health ministry has said.
In a bulletin, the health ministry reported 292 additional cases, bringing the total to 11,086.
It recorded seven more deaths, increasing the total to 726 while 75 more patients have recovered, bringing total recoveries to 1,999.
Lockdown instructions starting to 'unravel', Labour says
Labour leader Sir Keir Starmer has said the new lockdown instructions issued by the Prime Minister on Sunday were starting to "unravel".
"What I think everybody wanted to hear was something that was pretty clear and a sense of all the countries - England, Scotland, Wales - pulling together and we didn't get clarity," he told LBC radio.
"I accept that for some things, like when can a school open, that's going to be conditional, but on this business of going back to work, the suggestion was last night that people go back to work today if they can't work at home, but don't use public transport - and that's really difficult, particularly if you're in a city like London - and without guidelines in place as to how work places need to operate.
"You know, simple things like how do you keep people two metres apart? What about sanitation, protective equipment?
"These are things that were discussed in a consultation document last weekend but not resolved yet.
"I was actually quite surprised the prime minister said, effectively in 12 hours' time, start going back to work without those bits in place.
"We needed that clarity and it is unravelling a bit this morning because I think the foreign secretary has now said, 'Well, go back to work doesn't really mean until Wednesday', so suddenly it has shifted."

French passengers to be exempt from UK quarantine rules
Passengers arriving from France will be exempt from the UK coronavirus quarantine measures laid out by Boris Johnson in Sunday evening's televised address, Downing Street has confirmed, Rory Sullivan reports.
The prime minister announced last night that "it will soon be the time... to impose quarantine on people coming into this country by air" to prevent infection rates rising.
"No quarantine measures would apply to travellers coming from France at this stage," Mr Johnson's office said.
After the British prime minister spoke to French president Emmanuel Macron on the phone, both countries released statements saying that any measures would be taken in a “concerted and reciprocal manner”.

Social care workers have 'significantly' higher death rates, analysis suggests
People working in social care, including care workers and home carers, have "significantly" higher death rates involving Covid-19 than the working population as a whole, new analysis suggests.
For male social care workers in England and Wales, the rate of death involving Covid-19 is estimated to be 23.4 deaths per 100,000 males, while for female social care workers the figure is 9.6.
By contrast, for all males of working age (20-64 years old), the rate of death involving Covid-19 is 9.9 deaths per 100,000, with 5.2 deaths per 100,000 females.
The figures have been calculated by the Office for National Statistics (ONS), based on deaths involving Covid-19 in England and Wales registered up to April 20.
Lockdown fines to increase
The starting point for lockdown fines in England will rise to £100 from Wednesday.
The first fine will be lowered to £50 if paid within 14 days, according to the Home Office.
Fines will double for each repeat offence, up to a maximum of £3,200.
Existing legislation known as the Health Protection (Coronavirus, Restrictions) (England) Regulations 2020 will be updated from Wednesday to reflect the changes coming into force.
It is not yet clear if the same changes to fines will be adopted in Wales, Scotland and Northern Ireland.
