MPs and peers could personally finance a permanent memorial to Prince Philip on the parliamentary estate, with Conservative MPs rallying support for the proposal. One idea being discussed is for a memorial to be placed in the cavernous Westminster Hall, which dates back to the 11th century and is the oldest part of the estate. Another is for part of the Palace of Westminster to be renamed after the Duke, such as St Stephen's Entrance, which for many years was the arrival point for visitors. The early backing for a permanent memorial and one that is funded by parliamentarians reflects the high-esteem the Duke was held in by scores of MPs. It is understood Lindsay Hoyle, the House of Commons speaker, is open to proposals and will be monitoring the views of MPs over the coming weeks. Peter Bone, the Conservative MP for Wellingborough, told The Telegraph: "The Duke served the country for such a long period and in such a steadfast way. “Through all the ups and downs he’s always been there at the side of Her Majesty. When you come into ‘the mother of parliaments’ it would be rather nice that a memorial was there.” He added: “I think parliamentarians both in the Commons and the Lords would contribute. I think it’s something the speakers of both houses [of parliament] should look at.” Bob Blackman, joint secretary of the influential 1922 Committee of Tory backbenchers, also expressed support for a permanent memorial paid for by MPs and peers. “There certainly should be something in the Palace of Westminster as it is a royal palace,” Mr Blackman told this newspaper. “I think it would be absolutely right that we fund it through an appropriate collection from MPs and peers by voluntary contributions. That would be sensible.” There is precedent for such moves. A stained glass window to celebrate the Queen's Diamond Jubilee unveiled in 2012 was financed by members of the House of Commons and the House of Lords.
