Looking a wordometer for yesterday , UK has 220.000 cases and 4000 new ones last 24h , France has 180.000 cases but only 300 new cases yesterday , 170.000 and 500 new cases in Germany .
So this indicates clearly the pandemic has not yet peaked in the UK and lifting restrictions will only make matter worse. If I was a UK resident I would not be worried about air passengers coming from France or Germany ...but those coming on domestic flights ..
