Germany and Italy endured sweltering conditions on Saturday as a heatwave linked to dozens of deaths in Western Europe spread eastwards after temperatures broke records above 40C.
Britain, France, Switzerland and Germany have all experienced record heat in June, and the weather system could test more records as it rolls across Germany towards Poland.
Scientists said the heatwave would have been virtually impossible without man-made climate change, which has made this weeks night-time temperatures 100 times more likely than they would have been even two decades ago.
