Parts of South East without electricity due to widespread power cut

Large parts of London and the South East are without electricity because of a widespread power cut this evening.

The company has tweeted saying it is because of a failure on the National Grid network.

The power cut is affecting travel with train services including Thameslink trains being hit.

Trains between Stevenage and Kings Cross are at a standstill.

Traffic lights in some areas are also off and drivers are being urged to take extra care on roads.
