Britain will be gripped by a 35C heatwave from today bringing a 'rise in deaths' as the second five-day amber heat health alert in two weeks comes into force at midday.

The UK Health Security Agency (UKHSA) alert will last until Tuesday at 6pm and covers London, the East Midlands, South East, South West and East of England.

The alert covers Worthy Farm in Somerset, where the Glastonbury Festival is taking place and British band The 1975 are set to headline the Pyramid Stage this evening.

A yellow alert was also issued for Yorkshire and Humber and the West Midlands for the same time period amid fears of 'significant impacts' for health and social care.

Temperatures could hit 28C (88F) today in southern England, then rise to 30C (85F) tomorrow, 31C (88F) on Sunday, 35C (95F) on Monday and 30C (85F) on Tuesday.
