Covid: Boris Johnson says to 'think carefully' over Christmas mixing

Up to three households will be able to meet up during a five-day Christmas period of 23 to 27 December, leaders of the four UK nations have agreed.

People can mix in homes, places of worship and outdoor spaces, and travel restrictions will also be eased.

Prime Minister Boris John, speaking from isolation at 10 Downing Street, said people should make a "personal judgement" on the risks of meeting up.
