Boris Johnson indicated the lessons from the pandemic would be applied in the heatwave.

He told his final scheduled Cabinet meeting: “On another scorching, sweltering day I think it’s very, very important that we think back to that moment that we opened up (after the lockdown) and try and balance risk with the need to keep our country, our society and our economy moving.

“I hope, Cabinet, that you are all agreed that as far as possible we should keep schools open and keep our transport system going as far as we possibly can.”
