Not sure if this is the place, but I see the Mail online reporting that anyone flying into the UK will have to quarantine for 2 weeks. Haven't seen this reported anywhere else but have to say this would make sense (even more sense 4 weeks ago)
If this does come into force it's going to complicate future travel plans. Will have to rethink whether a one week trip is going to be worth having to home quarantine for 2 weeks upon arrival back in UK.
