Howard was returned unopposed for Steyning on the family interest in 1820, despite rumours that his brother, the 12th duke of Norfolk, would not bring him into Parliament again because of his refusal to vote against the Liverpool ministry’s Six Acts.
Described as a ‘fat bon vivant, an accumulation of many years’ turtle and venison’, Howard died in June 1824. He left Thornbury Castle to his only son Henry Howard*, and other real estate and the residue of personal estate sworn under £90,000 was divided between all his children.
