If you have spotted gritting lorries out on the roads during the heatwave, don't worry, you're not imagining things.

Councils across the south of England have been sending out gritters, usually associated with wintry conditions, to combat melting roads.

Walking up to the play area at 15:30 BST, it would normally be full of schoolchildren playing while their parents watched on.

Not today though ... deserted. The only word for it.
