A mutant strain of coronavirus sweeping across London and the South East of England has prompted the EU nations to start restricting inbound flights from the UK.

The German embassy in London tweeted that flight restrictions were the result of "the coronavirus mutation".
On Saturday, British Prime Minister Boris Johnson said there was "no evidence" the new variant "causes more severe illness or higher mortality" but "it does appear to be passed on significantly more easily".
He said the new strain could be up to 70% more transmissible than the old virus variant.
