It comes as forecasters in Europe said record temperatures being reached across the continent are being driven by a so-called ‘heat dome’ of warm air from northern Africa trapped under a high-pressure system.

Temperatures in Spain are expected to peak later this week at 38C, while parts of Italy have imposed restrictions on working outdoors.

Scientists say human-driven climate change is amplifying such extremes, with Europe warming faster than the global average and heatwaves growing more frequent and severe.
