In East Ham, east London, a baby girl was found abandoned in a shopping bag in park in near-freezing temperatures on Thursday evening.

Ovidijus Zvaliauskas found the baby with his mother, who was walking her dog.

He told BBC News it was so cold the baby had frost on her head. "There's no words for it. It's terrible," he said.

The newborn girl was taken to hospital and is said to be in a stable condition. Medical staff have been calling her Roman, as the play area she was found was situated just off Roman Road.

Parts of Cumbria have seen 8cm of snow, while there was 7cm recorded in Inverness-shire and 5cm in Powys.

Sammy Wheeler, who runs the Jamaica Inn, said some of those who spent the night had walked "a good three, four or five miles" through the snow to get there.

All 36 rooms at the pub were occupied overnight, with some shared by strangers. Two makeshift dormitories were also set up in the restaurant and lounge areas to help look after the guests, who included children and an eight-month old baby.

"People were incredibly high spirited," Ms Wheeler said.
