Selwyn inherited from his father a parliamentary interest of some importance. He could nominate to both seats at Ludgershall, and had a strong interest at Gloucester, which his father had represented from 1734 until his death in 1751. He declined an invitation to succeed immediately to his father’s seat, preferring to wait until the general election, and was then returned after a contest. The Ludgershall seats he used as a source of income, placing them at the disposal of each Administration in turn. When his interest at Gloucester collapsed in 1780, he took refuge at Ludgershall, and occupied one seat there for the rest of his life. In return for the support he gave Administration, he held three lucrative sinecures for the greater part of his life; between 1774 and 1782 he had an additional pension of £1,500.
Selwyn took little interest in strictly political matters: during 44 years in the House of Commons he never once spoke. His attitude to politics was that of a spectator, with little feeling for the realities behind the parliamentary struggle. On 1 Jan. 1782, to demonstrate how critical affairs were, James Hare wrote to Lord Carlisle:
Yet he was capable of exerting himself on behalf of his friends. He spent many hours advising Carlisle on his finances, and on 8 Dec. 1775, when the St. Johns had persuaded him to take the chair in committee on an enclosure bill, he wrote: ‘I have gained it seems great reputation, and am at this minute reputed one of the best chairmen upon this stand.’ Normally he was roused only by threats to his own position. In 1773 (28 Dec.) he was complaining bitterly of the ‘ill-treatment’ he had received from Grafton and North; on 16 Mar. 1782 he wrote: ‘Lord North and his secretary Robinson have acted such a part by me that I should never have believed anything but a couple of attorneys of the lowest class to have done.’ During the winter of 1781 his gambling losses were particularly severe: his usual placid good-humour deserted him, and he wrote (21 Mar. 1782) in violent terms of Fox and his friends, whose victory would jeopardize his sinecures: ‘the insolence, the hard heartedness, brutality, and stuff which these people talk, altogether gives me the worst apprehensions of what they will do’. A week later, he deplored their ‘impatience to get into lucrative places’, and sneered at Fox’s friends James Hare and Richard Fitzpatrick, complaining that they were jubilant at their party’s success: ‘when people of low birth have by great good luck and a fortunate concurrence of events been able to obtain, from lively parts alone, without any acquisitions that can be useful to the public, such situations as are due only to persons of rank, weight, and character, it is surely an easy task not to be insolent’. But he prepared to shuffle into line should it be necessary: ‘if the country becomes better and safer for their conduct, it would be folly not to assist them’ (29 Mar. 1782). To the end of his life, his concern was only for his own comfort. After the general election of 1790, when he was in danger of losing control of Ludgershall, his main worry was ‘that my hopes of any emolument to be derived from it will be frustrated, because, although I have done the utmost in my power to assist his Majesty’s ministers for three and forty years, I am become quite useless to them’.
Selwyn professed direct responsibility to the person of the King—‘my royal master’ he called him frequently. ‘I will have nothing to do with any persons who mean to act independently of the King’, he told Lord Holland, ‘for let my circumstances be what they may, I will belong to nobody else.’
Selwyn was a complex personality. ‘He has a great deal of vanity and loves to be admired and caressed’, wrote an Oxford don of him at the age of 25.
Selwyn died 25 Jan. 1791.
