Barnard was returned unopposed in 1790 for the Winchelsea seat recently bought by his father. He had joined Brooks’s in 1788 (he resigned in 1802, but was re-elected in 1816) and initially acted with opposition, but he supported Pitt in the new Parliament.
As a peer, he became alienated from Pitt, probably because the minister was unable or unwilling to promote him in the peerage. He gravitated to the Whigs, via the Carlton House party, though he turned Tory for a brief period in 1830.
He died, immensely wealthy, 29 Jan. 1842.
