In the 1857 United Kingdom general election, the Whigs, led by Lord Palmerston, won a majority in the House of Commons as the Conservative vote fell significantly. The election had been provoked by a vote of censure in Palmerston's government over his approach to the Arrow affair which led to the Second Opium War. Aged 72 Palmerston is the oldest person to win a general election for the first time in history.
There is no separate tally of votes or seats for the Peelites. They did not contest elections as an organised party but more as independent Free trade Conservatives with varying degrees of distance from the two main parties.
