A group of 40 UK politicians is pushing for British Telecom (BT) to slash its quarterly line-rental charges.

The members of Parliament today signed an Early Day Motion, demanding that BT chops up to £27 off its bills, reports the London Evening Standard newspaper.

BT, though, remains bullish, saying in a statement: "Yes, we've a standing charge - along with every other telecom company in the world."

BT carries 20 million residential lines in the UK, earning it more than £555 million a year before a single call is made.
