Starkey prefers radical changes to the UK's constitution in line with the federal system used by the United States, although in an interview with Iain Dale he expressed his support for the monarchy, the Queen and Prince Charles. In the run-up to the UK Alternative Vote referendum, he was a signatory on a letter to "The Times", which urged people to vote against the proposals. Starkey thinks the modern UK House of Commons has become a weak political institution and that it should return to its core value of being in defiance of state authority, as it was in its origin. He believes the House too often gives way to the state, such as with the police being allowed to search the place without a warrant. This occurred in 2008 with the searching of the Westminster office of Conservative politician Damian Green after the custodians of the House, the Speaker and the Serjeant at Arms, allowed the police to search the place without a warrant.
