Torrential rain and thunderstorms have caused flooding in parts of London and the South East of England as voters head to the polls for the UK’s EU referendum.
There was major disruption to the rail network across the region, with many routes blocked by standing water, while polling stations were hit by flooding.
A number of London Underground lines were also suspended.
The affected rail routes included services into London Victoria from East Croydon, London Waterloo via Surbiton and a variety of metro routes in south-east London.
Passengers travelling with operators such as South West Trains, Southern, Gatwick Express and London Overground suffered delays and cancellations.
A Network Rail spokesman said flash floods were rising in some areas and its engineers were also dealing with the aftermath of lightning strikes at Surbiton.
He added: “Our staff have been out all night and are still out in the rain working with pumps and repairing damage, and we are doing all that we can to keep trains running.”
The District line, DLR and London Overground were all suspended or delayed because of flooding.
Many of London’s roads were affected by localised flooding, including the North Circular, which was closed at Waltham Forest.
There were fears turnout for the EU referendum could be hit, but those fears could have been overstated if reports on social media of queues at polling stations are anything to go by.
The majority of posts are coming from London polling stations, pointing to a potentially good turnout in the capital.
Showers were expected to ease by 10am on Thursday morning before returning with similar intensity from 2pm.
The Met Office has issued an amber “be prepared” warning of rain for Buckinghamshire, Greater London, Kent, Surrey, Slough, Windsor and Maidenhead effective for later on Thursday.
A yellow warning covering the South East is in place until Friday.
Polling closes at 10pm.
