Millions more people will qualify for free coronavirus tests as ministers ramp up their “test and trace” plans in order to begin easing the lockdown.
The Government has announced that over-65s and their families would now be eligible if they are showing symptoms.
The new policy also covers workers who have to leave home.
In addition, care home staff and residents, NHS workers and hospital patients will be able to get a test even if they have no symptoms.
In total, roughly 25 million people in England should be able to find out whether or not they have the disease.
Health Secretary Matt Hancock said: “From construction workers to emergency plumbers, from research scientists to those in manufacturing, the expansion of access to testing will protect the most vulnerable and help keep people safe.
“It’s possible because we’ve expanded capacity for testing thus far.”

As ministers look at ways of getting the country back on its feet, pubs could reopen if they followed tough measures such as rationing drinkers to three pints, experts have revealed.

The terms are outlined in a plan by economist and government adviser Professor Eyal Winter.
Ministers were on Tuesday unable to say how many tracers have already been hired out of the 18,000 target while health chiefs said the accompanying NHS app would take another “two to three weeks” to be ready.

The Cabinet is meeting on Thursday to discuss “refining” the measures ahead of the next official review of the lockdown on May 7.

Business Secretary Alok Sharma has chaired meetings by sector in recent days amid concerns millions of people may be too fearful to return to work - even when they get the green light.
Mr Johnson has urged Tory MPs and businesses pressing for a swift end to the lockdown to “contain your impatience” as the country was at the “moment of maximum risk” from the deadly virus.
But he also promised to “fire up the engines” of the economy as soon as it is safe to do so.
In other measures, pubs could reopen if they followed tough measures such as rationing drinkers to three pints, experts have revealed.

Scotland, which has repeatedly given early hints of announcements in the rest of the UK, yesterday recommended the public wear face coverings or scarves - as opposed to masks - in limited circumstances such as in shops or on public transport.
But Mr Hancock claimed the science was “weak” on the effectiveness of face masks to prevent the spread of the disease while Government science chiefs suggested it would have a “small effect” on the outbreak.
The NHS phone app - which would run alongside ‘test and trace’ and could enable some lockdown measures to be lifted - will be ready for national roll-out in “two to three weeks”.
