Health Secretary Matt Hancock called for people to maintain social distancing to save lives in the first online press conference from 10 Downing Street.
The media briefing was conducted through video conferencing software with journalists asking questions from remote locations.
Appeal for hospital volunteers
Hancock revealed the government expects a temporary 4,000 bed coronavirus hospital to become operational next week in London’s Excel Centre, a massive exhibition hall complex. The Nightingale Hospital will become a critical care facility for the capital’s covid-19 patients as the NHS fears hospitals will be overrun.
He also appealed for 250,000 volunteers to work alongside the NHS and confirmed more than 11,000 retired doctors and nurses were returning to aid hard-pressed hospital staff.
Speaking in The Commons, Chancellor Rishi Sunak announced he was still working on a fair way to financially support the self-employed after a clamour of protests from freelance workers.
“There are genuine practical and principled reasons why it is incredibly complicated to design an analogous scheme to the one that we have for employed workers but I am determined to find a way to support them,” he said.
