Heatwave hits UK

The country braces for record-breaking temperatures. The head of the climate change committee discusses whether the UK is adapting fast enough to increasing temperatures, and we hear advice on schools, as hundreds prepare to close. As Keir Starmer commits to publishing the Defence Investment Plan ahead of next month's Nato summit, General Sir Richard Barrons discusses whether it would be better to wait for a new PM to be in place. And we hear from Washington DC, where its famous reflecting pool is drained once again, to remove algae.
