The House of Commons is to be installed with mains plugs to allow MPs to use their mobiles while they are supposed to be listening to debates.
Plans are being drawn up to fit 72 double sockets across the chamber.
The bill for the works on the Grade I-listed building is expected to top more than a whopping £5,000.

The move is likely to reignite concerns that MPs are too busy working on their mobiles and other handheld devices to listen to other Members during debates.
MPs were given the green light to take iPads and Blackberrys into the Commons chamber to 'tweet' comments during debates in March 2011.
They were told that the use of smartphones is permitted in the chamber – so long as they are on silent, and they do so 'with decorum and regard for others'.
