Sir Robert Peel's first government succeeded the caretaker ministry of the Duke of Wellington. It was a minority government, and relied on Whig support. However, this the Whigs felt disinclined to give, joining with the Irish radicals to defeat the Tories at every turn. After a reign of only four months, the government felt obliged to resign, whereupon the Whig leader Lord Melbourne formed his second government.

Members of the Cabinet are indicated by bold face.
