Prime Minister Boris Johnson has set out a three-point plan to prevent a second wave of coronavirus.
He said the Government was slowly reducing some elements of the lockdown - but was taking steps to prevent a second wave of Covid-19.
They are:
- Setting up a "test and trace" scheme to spot outbreaks of coronavirus, so that local lockdowns can be introduced in areas where the virus re-appears
- Introducing controls at UK borders, so that anyone who comes into the country has to quarantine for 14 days
- Working with other countries to provide more vaccines for diseases such as polio and measles in poorer parts of the world, so they are better able to cope with coronavirus.
Speaking at the daily Downing Street press conference, he said: "This is the moment really for humanity to unite in the fight against the disease"
Mr Johnson added: "This virus has shown how connected we are. We're fighting an invisible enemy and nobody is safe, frankly, until we all are safe."
He urged anyone who had coronavirus symptoms to get a test.
And he also said that if there was bad weather over the weekend, people should avoid any temptation to hold parties or meet friends indoors. The government has said up to six people can meet outdoors, including in private gardens.
Mr Johnson said: "Some of you may be tempted to move the gatherings you've been enjoying outdoors indoors, out of the rain. I really urge you, don't do that."
Evdience shows the risk of transmission are "much lower" outdoors and the risks of passing on the virus are "signifcantly higher" indoors, Mr Johnson said.
"Breaking these rules now could undermine and reverse all the progress we've made together."
There was a warning from Sir Patrick Vallance, the government's chief sceintific adviser, who explained that coronavirus was still a major threat.
He said latest figures showed 1,871 new cases of coronavirus had been confirmed in one day - but the real figure was "higher than this."
He said: "It could be somewhere around 8,000 a day".
And he said: "This is not coming down fast. And so we have relatively large numbers, still not coming down fast."
More than 50,000 people in the UK have now died of Covid-19, according to an analysis by the PA news agency.
Statistics published by the National Records of Scotland show that 3,911 deaths involving Covid-19 had been registered in Scotland up to May 31.
Figures published on Tuesday by the Office for National Statistics showed that 44,401 deaths involving Covid-19 had occurred in England and Wales up to May 22 (and had been registered up to May 30).
And the latest figures from the Northern Ireland Statistics and Research Agency, published last week, showed 716 deaths involving Covid-19 had occurred in Northern Ireland up to May 22 (and had been registered up to May 27).
Together these figures mean that so far 49,028 deaths have been registered in the UK where Covid-19 was mentioned on the death certificate, including suspected cases.
Between May 23 and June 1, a further 931 hospital patients who had tested positive for Covid-19 died in England, according to NHS England; while a further 78 people in hospital and care homes who had tested positive for Covid-19 died in Wales, according to Public Health Wales.
And in Northern Ireland, a further 22 people who had tested positive for Covid-19 died between May 23 and June 2, according to the Northern Ireland Department of Health.
These add up to a further 1,031 deaths that have occurred since May 23, and together with the total figure of 49,028 registered deaths, means the overall death toll for the UK is now just over 50,000.
