Veto veto ("withholding Royal Assent") was last exercised in 1708 by Queen Anne with the Scottish Militia Bill 1708. The House of Lords used to have an effective power of veto by refusing to concur in bills adopted by the House of Commons. However, reform first by a Liberal government and then by a Labour government has limited its powers. The Parliament Acts of 1911 and 1949 reduced its powers: they can now only amend and delay legislation. They can delay legislation for up to one year. Under the 1911 Act, money bills (those concerning finance) cannot be delayed, and under
Monarchy of the United Kingdom the Queen granted his request as Heath had already failed to form a coalition. The resulting general election gave Wilson a small majority. The monarch could in theory unilaterally dismiss the prime minister, but in practice the prime minister's term nowadays comes to an end only by electoral defeat, death, or resignation. The last monarch to remove the prime minister was William IV, who dismissed Lord Melbourne in 1834. The Fixed-term Parliaments Act 2011 removed the monarch's authority to dissolve Parliament; however the Act specifically retained the monarch's power of "prorogation", which is a regular feature of the parliamentary calendar.
