Monday 18 July sees both the next vote for the Conservative leadership contest and the first ever national emergency red alert for heat (England braces for 40C temperatures as experts warn thousands could die, 15 July). Let us hope that those Tory MPs who flirt with climate change denial feel the heat and have to lie down during voting hours.

• I can stand on one leg, eyes open or closed (Letters, 13 July). I don’t make marmalade, because other Guardian readers give us jars of the stuff, and I don’t tell people my age: I simply say I was born during the Baedeker raids on Bath, and they can look it up, if they can spell it.
