People across the UK have braved the temperatures and gone swimming outdoors to kick off their Christmas Day celebrations.

Hardy swimmers could be seen taking a dip in festive hats and costumes in The Serpentine, in London’s Hyde Park, early on Sunday morning.

Meanwhile, people in Tynemouth, in the North East, wore bikinis, swimming shorts and Father Christmas hats as they entered the sea at King Edward’s Bay.

Some were dressed as Christmas elves, while others donned Santa hats.

Some of those at Boscombe beach in Dorset also wore fancy dress while taking their early morning dips in a swim that raises money for Macmillan Caring Locally.

Meanwhile, in Birmingham, Blackroot Pool in Sutton Park hosted dozens of swimmers.
