Official: Last night in Bradford was warmest for 107 years

Daffodils can be seen already, as the UK could be set for the warmest December in almost 70 years

The city recorded a daily minimum temperature of 11.6C (52.88F).

December temperature records for at least the last 10 years were broken at 41 regional stations across England, Scotland, Wales and Northern Ireland on Wednesday night.

The highest overnight temperature recorded in the last month of the year was 15C (59F) at Hawarden Airport, Flintshire, in 1994.

The hottest December 16 in the UK was recorded in 1972 at Aber in Gwynedd, north west Wales, when it reached 17C, and Ms
