Mr Hancock says he has been advised that the degree of resistance against coronavirus for those who have recovered from it "is deemed to be very high, especially in the first year or more afterwards".

He says it is "good news that it is highly likely that once people have got it and recovered then they are going to be OK".

On calls for testing for all, the UK's health secretary says the test is "not reliable for people who are not symptomatic".

He says that is why testing at the airport, for example, is not effective and some of the countries that started doing that have stopped.

There are "loads of false positives" with temperature testing as the person "might be ill with something else", he says.

Or there are "loads of false negatives... because they don’t have enough virus in their system yet to be symptomatic".

"Testing of someone who does not have symptoms is not reliable and is counter-productive so we won’t be doing it."
