The government’s chief medical advisor, Professor Chris Whitty, has said that the UK will have to live with some disruptive social measures for at least the rest of the year.

He said: “It was wholly unrealistic to expect that live would suddenly return to normal any time soon”.

He also said: “In the long run the ideal way out would be via a highly effective vaccine or drugs to treat the disease”.

But he also warned that the chance of having those within the next calendar year was “incredibly small”.
