MPs are calling for the tower housing Big Ben to be renamed in honour of the Queen's Diamond Jubilee.
Twenty-three members have signed a Commons early day motion calling for the Clock Tower at the Palace of Westminster to be formally named the Elizabeth Tower.
The motion was tabled by Conservative Tobias Ellwood and has the backing of MPs from the three main parties, including former foreign secretaries Jack Straw and Sir Malcolm Rifkind.
Sally Biddulph reports on an idea that is gathering momentum, but leaves some people confused.
Such a move would not be without precedent.
When the Palace of Westminster was rebuilt in 1860 the west tower, known as the King's Tower, was renamed the Victoria Tower to commemorate the Queen's long reign.
