The Met Office has issued a rare red weather warning for extreme heat across 50 areas of the UK this week, with temperatures expected to reach up to 40°C in some places. The warning, which covers large parts of England and Wales, will be in effect from 9am on Wednesday, June 24, until 9pm on Thursday, June 25.
