EU officials are discussing a joint response to a new, more infectious Covid-19 variant in the UK, which has sparked travel bans by many countries.
Canada and India joined European states in blocking flights from the UK while Europe-bound train services via the Channel Tunnel have been halted.
The new variant is said to be up to 70% more transmissible, but there is no evidence that it is more deadly.
There is also no proof to suggest that it reacts differently to vaccines.
