He was very interested in the government of Britain, and worked closely with prime ministers such as Lord North and William Pitt. He was strongly opposed to American independence, and was blamed by the public for losing the war of the American Revolution. He suffered from illness for some periods of his life and in 1811 he became so ill that his son was made Prince Regent.
