Rishi Sunak has announced long-awaited state help for the self-employed, following figures that showed nearly one-quarter of them had been living in relative poverty even before coronavirus struck.

Sadiq Khan has responded to the chancellors self-employed scheme like many officials - praising the substance while raising concern over its timing.
"Today's announcement by the Chancellor is welcome and will help millions of people," Mr Khan tweeted.
"However, June is some time away and concerns remain that many self-employed and freelancers could be excluded in London, where the cost of living is higher than elsewhere.
"Whether applying for Universal Credit or accessing this new support, having to wait weeks or even months risks leaving people unable to pay bills and put food on the table.
"I'll continue to urge Govt to provide the right levels of financial help as soon as practically possible."
There are now 11,658 positive coronavirus cases in the UK, with 578 deaths.

However criticism has been levelled due to the time it may take to see the scheme take force.

"Our main priority is to take care of people's lives, not forgetting the responsibility of managing the economy," they wrote.
Lizzy Buchan reports on parliament's Health and Social Care Committee, which is hearing evidence on the nation's response to Covid-19
Dr Chaand Nagpaul, chairman of the British Medical Association, has told parliament's health and social care committee the failure to test NHS staff was “illogical” and hampering efforts to fight the disease as many staff were self isolating without knowing if they had the virus.
He told the committee: "At this time of year, it is estimated that 10% of the population could have a symptom of a temperature or a cough in a non-Covid situation.
"We had situations where many GP practices and hospitals were understaffed, the staff themselves who were self-isolating were telling us they felt able to work but were following the guidance, and that if they were able to be tested they would come back to work.
"It seems counter-intuitive that we are reducing our workforce when we need our NHS workforce the most.
"On 16 March we heard from the prime minister an announcement that healthcare workers would be prioritised but that hasn't materialised."
Cambridgeshire Police has recieved a spate of calls from the public asking for more information on movement restrictions deployed to stem the spread of the virus.
She said there will be "a million tests that people can do themselves", adding: “In other words, members of the public will be able to take a blood test and send it back in the post and get that analysed.”
She told the health and social care committee: “That is an antibody test that tells you if you have had the condition.
"That is absolutely critical for two reasons: to understand what it is going on but also to allow people to return to work.
"That is well advanced but not ready yet. We need to be absolutely sure it is a valid test.
"We expect that to come within a couple of weeks but I wouldn't want to over promise on that, and I think the chief medical officer [Prof Chris Whitty] has been absolutely clear on it being right before it is put out."
Her comments came after medical experts sparked confusion on when such tests could be ready. Prof Sharon Peacock, of PHE, said millions of tests could be available within days on Wednesday, but the chief medical officer later took a more cautious stance, saying the tests would not be ready until the government was certain they were accurate.
MPs have criticised the chancellor's pledges to support the self employed - particularly that people will be unable to claim until June.
Labour MP David Lammy tweeted: "Leaving the five million self-employed Brits without any support until June is a slap in the face. Many will be bankrupt by then. And why is there an eligibility cap for the self-employed but not the employed? This is not what I call fair."
SNP MP Stephen Flynn tweeted: "I did hear June. What on earth are they doing. My constituents simply cannot wait until June. They need help, now. No wonder he didn't announce it in Parliament yesterday."
Liberal Democrat MP and leadership candidate Layla Moran posted: "80% grant for the self-employed is welcome. But waiting until June does not give self-employed parity with those in employment."
Afghanistan has released 10,000 prisoners over the age of 55 to prevent the further spread of the virus, following on from a similar initiative that was rolled out by neighbouring Iran.
A spokesperson for president Ashraf Ghani's office said: "The president has issued a decree that several thousand prisoners will be released soon due to coronavirus".
The 10,000 will not include members of the Taliban or ISIS.

Australian scientists have found viruses similar to the one that has caused the global pandemic in trafficked pangolins.
A study from the University of Sydney found the SARS-CoV-2 virus, which cases Covid-19, is genetically similar to a strain effecting Malayan pangolins in southern China.
While unproven, it is believed the virus may have originated in a wild animal market in the city of Wuhan.

Created in 2009, the 18 page plan says those suffering from end stage organ failure due to underlying health conditions from cancer to severe burns will not be offered the devices.
