What has the Met Office said about UK heatwave?

The Met Office has described the weather as “unprecedented”.

The forecaster has said a new temperature record is “pretty likely” to be recorded.

“We’re looking at the maximum temperatures somewhere between 40C-41C, and that’s looking to be across the Lincolnshire and Yorkshire region,” Met Office meteorologist Annie Shuttleworth said.
