Torrential rain and flash flooding cause travel chaos

Lightning strikes, hail, torrential rain and flash flooding have caused major travel problems across east and south-east England.

There have been problems on the roads in Sussex, Essex and London.

London Fire Brigade said it was helping people trapped in their cars across parts of the capital.

Electrical supply problems caused by a lightning strike have led to disruption on Southern railways, with services subject to delays.

BBC Weather's Darren Bett explains the causes behind the adverse conditions.
