(16)The landmark clock tower containing Elizabeth Tower at Britain’s Palace of Westminster, is tilting. It is said the mother of all parliaments was slipping into the River Thames, raising fears over its future. "The tilt is now just about visible," said John Burland, a senior research investigator from Imperial College London who has worked on Elizabeth Tower and the Leaning Tower of Pisa. "You can see it if you stand on Parliament Square and look east, towards the river. I have heard tourists there taking photographs saying ’I don’t think it is quite vertical’—and they are quite right," he told the Sunday Telegraph.
    The House of Commons commission, which is responsible for the upkeep of the 19 th century neo-Gothic parliamentary estate popular with tourist photographs, was dye to meet Monday. Media reports said it would discuss a surveyor’s report which could recommend lawmakers move out for repairs costing up to one billion pounds, while the Daily Telegraph said another proposal might be to sell it to Russian developers for about 500 million pounds($ 779. 7 million). But a commission spokesman said there was no surveyor’s report,(17)and the members were only meeting to discuss setting up a group to look at the general long-term renovation of the Grade I -listed building designed by Charles Barry and Augustus Welby Pugin. The 96-meter tall clock tower, which houses the bell originally nicknamed Big Ben, leans about 46cm to the left of its peak. A construction expert who worked on the Leaning Tower of Pisa in Italy and a multi-storey carpark under the houses of parliament in central London, said there was nothing to worry about.(18)The tower would take 10 000 years to reach an angle of concern.
