The Regent let his ministers take full charge of government affairs, playing a far smaller role than his father. The principle that the prime minister was the person supported by a majority in the House of Commons, whether the king personally favoured him or not, became established. His governments, with little help from the Regent, presided over British policy. One of the most important political conflicts facing the country concerned Catholic emancipation, the movement to relieve Roman Catholics of various political disabilities. The Tories, led by Prime Minister Spencer Perceval, were opposed to Catholic emancipation, while the Whigs supported it. At the beginning of the Regency, the Prince of Wales was expected to support the Whig leader, Lord Grenville. He did not, however, immediately put Grenville and the Whigs into office. Influenced by his mother, he claimed that a sudden dismissal of the Tory government would exact too great a toll on the health of the King (a steadfast supporter of the Tories), thereby eliminating any chance of a recovery.
