A huge power cut has brought travel chaos to parts of London and the Home Counties.
Train lines have been hit by the power failure, with Transport for London also warning traffic lights have been affected.
Airports in the region are also said to be affected by the loss of power.
UK Power Networks has said large parts of the country are without power, with Liverpool being one of the cities affected.
Elsewhere in the north west, Stockport and Ellesmere Port are said to be without power.
The company tweeted on Friday evening: “We’re aware of a power cut affecting large parts of London and South East.
“We believe this is due to a failure on National Grid’s network, which is affecting our customers.”
