He sat in the House of Commons from 1660 until 1676, when he inherited the dukedom. He was an adherent of James II and lost his public offices following the Glorious Revolution of 1688. He is also an 8th great-grandfather to King Charles III.

He later accompanied his father into exile, but returned to England in 1647 to help recover his family estates. He was generally inactive, but was appointed to 22 committees. By 1664 he was listed as a court dependent and he seconded the motion of Sir John Goodricke, 1st Baronet to gift £120,000 to James, Duke of York for his naval services.
