The Big Ben clock tower has been renamed Elizabeth Tower by the House of Commons in honour of the Queen and her Diamond Jubilee.
It follows a campaign, reported on by LondonNet in March, backed by most MPs and the three main party leaders, started by Tory MP Tobias Ellwood.
Previously, the tower that housed the Big Ben bell was known as St. Stephen's Tower.
The successful Commons motion called for "recognition of Her Majesty's 60 years of unbroken public service on behalf of her country".
Ellwood said previously: "I can't think of a greater tribute for Parliament to bestow on Her Majesty than the naming of such a landmark."
Big Ben is the nickname for the great bell of the clock, though it is generally extended to refer to the tower as well.
