Amazing photographs have captured how huge swathes of central London were plunged into darkness due to a major underground fire.

An incredible aerial shot taken from the London Eye shows the area affected by the power cut almost completely blacked out after the blaze in Holborn.

Other eerie images showed buildings on the north side of the Thames shrouded in darkness as the fallout from the fire continued into the night.

There were also power cuts affecting large swathes of east London, including parts of Shoreditch and Bethnal Green, which UK Power Networks said was not related to the blackout in Holborn.

A spokeswoman said: "UK Power Networks engineers have restored power to 1300 customers in the Covent Garden area, after an incident damaged underground cables at Kingsway.

"About 1900 power supplies in the area were originally interrupted. Crews are currently working hard to excavate and isolate the damaged parts of the network, then re-route power to the remaining 600 customers overnight.

"It can be difficult to excavate in central London but provided this work can be completed we should not need to isolate supplies tomorrow morning when demand for power increases again.

"We are also working to help the emergency services investigate the cause."

It came after a major underground fire caused chaos in central London.

Offices were evacuated of around 2,000 workers after smoke and flames were seen emerging from manhole covers in Kingsway.

UK Power Networks confirmed the blackout was ongoing this evening and could not immediately provide a time frame of when electricity would be restored.
