Aberdeen ministry

After the collapse of Lord Derby's minority government, the Whigs and Peelites formed a coalition under the Peelite leader Lord Aberdeen. The government resigned in early 1855 after a large parliamentary majority voted for a select committee to enquire into the incompetent management of the Crimean War. The former Home Secretary, Lord Palmerston, then formed his first government.

† After June 1854 office became Secretary of State for War.
