Michael William Coplestone Dillon Onslow, 7th Earl of Onslow, styled Viscount Cranley from 1945 to 1971, was a British Conservative politician.

The House of Lords Act 1999 is an Act of the Parliament of the United Kingdom that reformed the House of Lords, one of the chambers of Parliament. The Act was given Royal Assent on 11 November 1999. For centuries, the House of Lords had included several hundred members who inherited their seats ; the Act removed such a right. However, as part of a compromise, the Act did permit ninety-two hereditary peers to remain in the House. Another ten were created life peers to enable them to remain in the House.
