William Gage came of an old Sussex family, whose estate at Firle gave them a natural interest at Seaford. A former follower of the Prince of Wales, Gage joined the Pelhams after the Prince’s death; and in 1754 with Newcastle’s support was returned unopposed for Seaford. In 1755 he was appointed paymaster of pensions, and on 2 Nov. 1756, shortly before Newcastle resigned, wrote to him:
Henceforth his politics were directed by two aims: to retain office and to obtain a British peerage. In June 1766 Rockingham supported his claim to a peerage, and the King promised to consider Gage when new peers were made.
Early in 1768 Gage expected to receive his British peerage at the dissolution of Parliament, and began discussing with Newcastle his successor at Seaford. But when he did not obtain his peerage he stood again at Seaford, and was returned unopposed. At a by-election in November Gage was invited by the Duke of Richmond and Lord Pelham to stand for the county, and at first accepted. But a week before the county meeting he informed Richmond that he must decline: ‘he says’, wrote Richmond to Pelham, 22 Nov. 1768, ‘he is sure that no man will refuse to let him off his engagement to the meeting when he tells him his story. That every man he has spoke to says he is perfectly in the right.’
Henceforth Gage voted consistently with Administration and eventually received his British peerage. Only two speeches by him are recorded during nearly 30 years in the House of Commons: for a motion on Hanoverian troops, 29 Mar. 1756,
He died 11 Oct. 1791.
