After the suicide of Castlereagh in 1822, the Tory Cabinet of Robert Banks Jenkinson, 2nd Earl of Liverpool began to split along political lines. The more liberal wing of the Tory government made some ground, with George Canning becoming Foreign Secretary and Leader of the House of Commons, William Huskisson advocating and applying the doctrines of free trade, and Catholic emancipation emerging as an open question. Although Palmerston was not in the Cabinet, he cordially supported the measures of Canning and his friends.
