In the 1857 United Kingdom general election, the Whigs, led by Lord Palmerston, finally 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 became the oldest person to win a general election for the first time. As of 2024 there has been no person as old as Palmerston to win a general election for the first time.
