Why Famous: William Cavendish-Bentinch, Duke of Portland was a Whig politician who was Prime Minister twice, with a record 24 years between each term of office.

Cavendish-Bentinck was first elected to parliament in 1761 before entering the House of Lords a year later when he inherited the dukedom from his father.
