The previous Palace of Westminster was also the site of a prime-ministerial assassination on 11 May 1812. While in the lobby of the House of Commons, on his way to a parliamentary inquiry, Spencer Perceval was shot and killed by a Liverpool merchant adventurer, John Bellingham. Perceval remains the only British Prime Minister to have been assassinated.
On 11 May 2010, following the resignation of Gordon Brown as Prime Minister and on his recommendation, Queen Elizabeth II invited Cameron to form a government. At age 43, Cameron became the youngest Prime Minister since Lord Liverpool in 1812, beating the record previously set by Tony Blair in May 1997.
Cameron outlined how he intended to "put aside party differences and work hard for the common good and for the national interest." As one of his first moves Cameron appointed Nick Clegg, the leader of the Liberal Democrats, as Deputy Prime Minister on 11 May 2010.
