Three households will be allowed to mix for up to five days in a plan to allow families to reunite at Christmas, Government sources said.

Relaxed restrictions will apply from December 23 and last until December 27 and mean families can travel from one part of the UK to another.

This is the breaking news from the Press Association, with more on this to follow. 

It follows a Cobra meeting between all four UK governments will be held on this afternoon to agree on a four-nation approach to relaxing coronavirus restrictions over the festive period.

Speaking earlier today, Transport Secretary Grant Shapps said the nations were "very close" to coming to a joint agreement.

He also urged people to “look very carefully” at how they will go home for Christmas – and even consider not travelling.

In England, the Government has already announced new tiered restrictions which will come into effect on December 2 and could last until the end of March – apart from the Christmas relaxation just revealed. 

On Thursday, people in Cornwall and England will find out which tier they are being placed in once the lockdown ends.

More regions than before the lockdown are expected to face Tier 2 or Tier 3 restrictions, banning simple acts such as popping to the pub for a pint of beer or a glass of wine.

In Tier 2, alcohol can only be consumed with a “substantial meal” while in Tier 3 pubs and restaurants will only be able to offer takeaway or delivery services.
