Prime Minister David Cameron, Nick Clegg and Ed Miliband have backed the proposal for parliament to bestow the extraordinary tribute on Queen Elizabeth to mark her six decades on the throne, the Daily Mail reported.
The House of Commons Commission, British Parliament's governing body, will meet by the end of this month and is expected to agree that the 96-metre clock tower should be renamed 'The Elizabeth Tower'.
A total of 331 MPs have now signed up to a campaign to mirror a tribute bestowed on Queen Victoria, the present Queen's great-great grandmother and the only other monarch in history to mark a Diamond Jubilee, it said.
The square tower at the other end of the Palace of Westminster, previously known as The King's Tower, was renamed The Victoria Tower to mark her long reign.
