An opposition MP has demanded “urgent” government action over fears that Freeview services will be disrupted by 4G mobile signals.

Shadow minister for media and telecommunications Helen Goodman said time was running out to find a solution to the problems likely to be caused by the rollout of the new mobile network.

There is mounting concern that the launch of 4G in 2013 could affect up to 2.3 million Freeview homes.

In a letter to culture minister Ed Vaizey, Goodman said: “More than two months have now passed since [Ofcom’s consultation] closed but Ofcom are yet to respond… and bring forward recommendations.

“There is a real danger that unless urgent action is taken, millions of viewers will see their Freeview services disrupted. This would be completely unacceptable.”

Goodman asked Vaizey to resolve the issue before Parliament’s summer recess.
