Britain was plunged into a deep freeze over the weekend as temperatures plummeted into double figures below zero.
Minus 11.7C was recorded at aptly named Chillingham Barns in Northumberland on Sunday night, the coldest temperature in England and Wales this winter.
The icy conditions spread all the way south, from -10.8C in Leeming, North Yorkshire, to -10.3C in Benson, Oxfordshire, and -9.9C in Odiham, Hampshire.
The freeze created a temporary challenge for rock climbers at Kinder Downfall in the Derbyshire Peak District. The site is normally home to a spectacular 30ft waterfall but it had frozen solid in the sub-zero temperatures.
