The contract to provide Wi-Fi access to London Underground stations has been awarded to Virgin Media.

The mobile internet service will be rolled out initially to 80 Underground stations by July in preparation for the Olympics, and to 120 stations by the end of the year.

The service will be free to Virgin Media customers after the Olympic Games, and will provide limited free content from the Tfl and full mobile internet to non-Virgin users via a pay-as-you-go plan.

London mayor Boris Johnson, said: "Millions of passengers will now be able to connect to their work, friends or access the latest news and travel information whilst on the move."
