There is disruption on Great Northern and Thameslink rail services after a major power cut in the south east of the UK.

The outage - which has affected rail services and airports - happened at about 5.30pm.

UK Power Networks said: "We're aware of a power cut affecting a large area of London and the south east due to an incident on the national transmission system."

Power is now back on in some parts, but trains are still affected - and services may be cancelled, delayed or revised until the end of the day.

UPDATE 6.50pm: Great Northern have tweeted: "Our advice right now is do not travel. We are unable to provide a service at present, please delay your journey for now and check back for updates.

"It is not clear at this point when services will be restored."
