Raining on Keir's parade! Britain is battered with downpours as nearly an inch falls in an hour and sparks travel chaos in London... and there's more to come with a weekend washout on the horizon

Keir Starmer's first day as prime minister was met with miserable weather as rain swept across the UK lashing Henley Regatta, Wimbledon and other usually summery events with heavy showers. 

Nearly an inch of rain fell in an hour in London on Friday afternoon sparking travel chaos across the capital. 

Golders Green tube station in north London was forced to close just before rush hour due to flooding, TfL announced on social media. 

And more wet weather is on the way this weekend with the Met Office predicting everyone will see rain at some point.

A yellow weather warning for rain is also in place across parts of Scotland from 10pm on Friday night until 10am on Saturday morning. 

The Met Office has warned the heavy rain may cause some disruption to travel as it sweeps across the north of the country.

The start time for Friday's matches was initially delayed until 12.15pm and was later pushed back even further to 1pm. 

Rain has caused persistent delays to play on the outside courts at this year's Championships with Wednesday's schedule affected as well.

People lined the stands in raincoats, ponchos and umbrellas as London was battered by persistent rain on Friday evening.

Tonight, the rain is expected to turn heavy across southern England and Wales, pushing eastwards overnight, according to the Met Office forecast.

Overnight, the heavy rain is predicted to move from southwest England towards central and eastern parts - producing plenty of wet roads and spray.

Further heavy showers will also affect parts of northern and western Wales and northeast Scotland - which has been placed under a Yellow National Severe Weather Warning from 10pm Friday until 10am on Saturday morning.

This means flooding of a few homes and businesses is possible, while journey times for motorists and public transport users will be increased due to water pooling on roads and train tracks.

Frank Saunders is a Chief Meteorologist at the Met Office. He said: 'An area of heavy and quite persistent rain will develop across parts of north and northeast Scotland later on Friday evening. This will continue overnight before turning showery on Saturday morning.

'It is possible that 20-30mm of rain is likely to fall quite widely in around 12 hours, but there could even be up to 50 mm in a few areas.'
