Thunderstorms and flash flooding cause traffic chaos

Dramatic thunderstorms and torrential rain is causing flash flooding across southern parts of England after a month's rain fell in just a few hours. Here's Laura Tobin's report.

Severe flood warnings have been issued by the Met Office which has waterlogged many rail stations and roads.

Earlier this morning a train derailed near Watford Junction after a landslide causing major disruption to services in and out of London Euston station. There were no reports of any injuries after the 6.19 service from Milton Keynes to London Euston came off the track at around 7am.
