| Westbury | 1780 |
Sheriff, Hants 1785–6.
In 1780 Gardiner was mentioned as a candidate for Oxford, but declined rather than injure the interest of his friend, Captain Bertie;1Advertisement, 6 Sept. 1780, Bodl. mss Top. Oxon. c.280. he was then brought in for Westbury by Lord Abingdon. He voted with Opposition in each of the five recorded divisions, 12 Dec. 1781-15 Mar. 1782; for Shelburne’s peace preliminaries, 18 Feb. 1783; and against Fox’s East India bill. He was classed as a supporter of Pitt both in Robinson’s list of January 1784 and in Stockdale’s of 19 Mar. Nevertheless, by the general election he was on bad terms with Lord Abingdon, who refused to re-elect him for Westbury.2‘An Open Letter’, ibid. There were persistent reports that he would stand for Oxford against Lord Robert Spencer and Peregrine Bertie: on the eve of poll they put out a handbill warning voters not to imagine that Gardiner was a friend of the Berties—‘no man ever behaved with more ingratitude towards the Abingdon family than Sir John’.3Ibid. But on polling day he did not come forward. In 1790 the Reading Mercury and Oxford Gazette carried a denial that he intended to offer himself again for Oxford. He was prominent in hunting and racing circles.
He died 18 Nov. 1797.
