UK Swelters as Heatwave Tests Grid

Britain is enduring its third heatwave of the summer, with temperatures matching 1976 records and the national grid operator warning that the country was on the brink of shutdowns on June 23.

Yellow heat health warnings remain in force for seven regions.

A hosepipe ban has come into effect across six counties, and forecasters say temperatures could reach 36°C in parts of the Midlands and South West.

The Met Office expects the extreme heat to ease slightly over the weekend before surging again.
