Doubt has been cast over the proposed development of a London-wide wireless broadband network, it has been reported.

Last month, Mayor of London Boris Johnson announced his vision for a network of Wi-Fi hotspots on "every lamppost, every bus stop" throughout the capital.

However, a spokesperson for the Mayor's office has now suggested that the project may not go ahead.

Speaking to PC Pro, they stated: "Boris Johnson is ambitious about making this happen, but really we're not saying how this might be rolled out or even that it is going to happen.

"The Mayor is passionate about access, but all he has done so far is mention it in a couple of meetings to see what people thought."

Earlier this week, Mr Johnson claimed that Wi-Fi services may soon be available on the London underground network.
