A huge power cut has hit the UK, with trains, tubes and traffic lights cutting out across the country.
Britain was plunged into darkness at rush hour with large parts of London, the South East, Liverpool, Glasgow and Greater Manchester all without electricity.
Thousands of homes have experienced power cuts while train lines, tube stations and airports have also been affected.
Train services in and out of London, including Thameslink, Southern and Gatwick Express are facing delays and cancellations.
Tube passengers in London reportedly collapsed due to heat exhaustion after a train was stuck between Oxford Circus and Green Park for 25 minutes.
Police have scrambled to stations in the capital to deal with the fall out.
A British Transport Police (BTP) spokesman said: “We currently have BTP officers assisting at several stations owing to current disruption caused by power issues.”
Network Rail said power outages had meant their signals had gone down, results in cancellations and delays in the Newport, Gloucester, Ashford, Bristol, Eastbourne, Hastings, Three Bridges and Exeter areas.
Rail operator Thameslink said many of its trains were “at a stand”.
Western Power Distribution (WPD), the electricity distribution network operator for the Midlands, South West and Wales, said there was a “major incident”.
Commuters in Liverpool as well as Ellesmere Port and Stockport in Cheshire also complained of power outages.
Passengers reported being “thrown off” an escalator after it suddenly stopped in Bradford, West Yorks.
Meanwhile, commuters were plunged into darkness on a packed train in Battersea, South West London.
Trains between Kings Cross in central London and Stevenage, Herts, are reportedly blocked due to a lightning strike.
There are also reported outages in the North East, Wales and Gloucestershire.
Meanwhile homes in East London were plunged into darkness and mobile phones and internet down.
