People have been urged to be cautious of the risk of spreading coronavirus when rules are relaxed over Christmas.

Up to three households will be allowed to stay together and form a "Christmas bubble" from 23 to 27 December, as agreed by all four UK nations.

Prime Minister Boris Johnson told people to use "personal judgement" on whether to visit elderly relatives.

A scientific adviser to the government said the relaxation of rules amounted to "throwing fuel on the Covid fire".

The measures will see travel restrictions across the four nations, and between tiers and levels, lifted to allow people to visit families in other parts of the UK.

Anyone travelling to or from Northern Ireland may travel on the 22 and 28 December, but otherwise travel to and from bubbles should be done between the 23 and 27.

People will not be able to get together with others from more than two other households, and once a bubble is formed, it must not be changed or be extended further.

The guidance says a bubble of three households would be able to stay overnight at each other's home but would not be able to visit hospitality, theatres or retail settings.
