In 1831, Coke's personal friend Earl Grey became Prime Minister; as a result, Coke's appearances in Parliament became more regular. He expressed delight at the Great Reform Act 1832, although he only spoke on the subject once, and chose its passage on 4 June 1832 as the appropriate moment to retire as an MP. As the "greatest commoner in England", Coke finally accepted a peerage in July 1837 (having been offered one six times before), becoming the Earl of Leicester. He took no pleasure in attending the House of Lords, however, describing it as "the hospital for incurables".
