Free wi-fi at some London Underground stations has now been turned on.

Transport for London (TfL) said people at King's Cross and Warren Street Tube stations will now be able to pick up the internet at ticket offices, escalators and platforms.

On Friday, Oxford Circus and Green Park Tube stations will go live, followed by Victoria and Euston on Saturday.

By the end of July, 80 stations will have wi-fi access, with 120 expected by the end of the year.

Virgin Media will run the service which will become a pay-as-you-go offering after the Olympic and Paralympic Games.

Virgin Media's mobile and broadband customers will be offered continued access as part of their subscriptions.

Non-paying users will be limited to a site showing online travel information and some free news and entertainment.

Mayor of London Boris Johnson said: "We need to ensure London is able to cement its position as Europe's leading digital city.

"Our partnership with Virgin Media to make wi-fi available on Tube platforms will be of tremendous benefit as building world class connectivity is critical to supporting new businesses and the jobs they create, especially in the high-tech and creative sectors."
