Thunderstorms and torrential rain have swept across parts of southern Britain, with lightning flashing across the sky.

Around 15,000 lightning strikes were recorded in four hours on Saturday night, BBC Weather said.

Stansted Airport reported delays to flights on Sunday morning after a lightning strike briefly left its aircraft fuelling system "unavailable".

The Met Office has issued a yellow warning for heavy rain and flooding across Wales and most of England.

Firefighters were called to a house in Stanway, Essex in the early hours of Sunday after a lightning strike set its roof ablaze.

Crews worked until 04:30 BST to extinguish the fire. No injuries were reported in the incident.

Later in the morning, storms brought more than an inch of rain to parts of Wales and the Midlands in just an hour.

Parts of Wales and central and southern England could see further thunderstorms on both Sunday and bank holiday Monday, with the Met Office warning of the possibility of power cuts and delays to trains and buses.
