Plans to extend the Northern Line to Battersea were backed by the Government today after a billion-pound funding package was approved.

The Department of Transport's decision means construction could begin as early as 2015.

The extension will create a new stop at Battersea Power Station and another on Wandsworth Road.

Journey times from the West and the City could be cut to 15 minutes from Battersea.

Last month a public inquiry was launched with an independent inspector investigating evidence submitted by Transport for London, individuals and organisations.

After the public inquiry planning powers need to be obtained from the Government.

It is hoped the new line will aid the regeneration of Nine Elms, supporting the creation of 25,000 new jobs and 16,000 new homes.
