Four deaths in the space of 19 months made Vane Tempest an extremely wealthy young man. Although his father had been created a baronet in 1782, he did not come into possession of the old family property at Long Newton until the death of his bachelor elder brother Lionel Vane in February 1793. A month earlier, the only son of this Member’s maternal uncle John Tempest, Member for Durham, died. In his will, dated 31 July 1793, Tempest left Wynward and all his other extensive property in Durham, which contained valuable coal mines at Rainton and Pittington, to his nephew, on condition that he took the additional name of Tempest. He succeeded to Long Newton and the baronetcy in June 1794 and to the Tempest inheritance two months later. He subsequently sold part of it, the Brancepeth estate, to William Russell for £75,000.
Vane Tempest was returned unopposed in his uncle’s place in October 1794, though it was later alleged that because of ‘his long absence in a foreign country, his precarious health, and the total want of intelligence, the knowledge of his existence was rendered extremely doubtful’ at the time.
In February 1800 he vacated his seat, ‘the necessity of attending to my private concerns requiring my presence in Ireland’, as he claimed, though it was thought that he was hoping to set himself up for an Irish peerage. In his place at Durham he secured the return of his Whig brother-in-law Michael Angelo Taylor, but only after a contest with William Russell’s son which cost £17,191. Soon afterwards he offered 37,000 guineas at auction for the borough of Gatton, but he was outbid by William Moffat.
Two weeks after his election he was reported to have died, but he survived a severe illness. He was given periods of sick leave, 24 and 30 Mar. 1808.
Sir H. V. Tempest has favoured me with a great deal of his correspondence respecting some offices ... at Durham ... for which Wharton and him have been competitors. It appears that they have been invariably given to the Member for the town. This I have represented to Sir H. V. Tempest: he is not satisfied, and it has ended in a letter in which he complains of ill treatment from the present government, and as far as I can understand the remainder, it means in plain English to say that he shall vote against us in the next session.
On 2 Dec. 1808 Vane Tempest complained to Sir Arthur Wellesley that his wife’s claims to patronage in Antrim had been ignored, and went on:
I confess I feel reluctance in forwarding her wishes nor could anything have induced me to have done so had I not found, upon a very recent occasion, that the rule ... of giving appointments to Members, for counties had been most carefully and ... intentionally broken through in my own instance. I beg leave to add that if it creates the least difficulty to the present government to allow me to stand on the same footing which the late Marquess of Antrim did with regard to his own estate and about which there has already been considerable hesitation, I may be told so at once, as by that means much trouble may be saved on both sides.

He voted against government on Cintra, 21 Feb., the Duke of York scandal, 17 Mar., and Castlereagh’s alleged electoral corruption, 25 Apr. 1809. The Whigs listed him among the ‘doubtful’ in 1810, when his only recorded votes were for the release of John Gale Jones, 16 Apr., and for parliamentary reform, 21 May. His only other known vote in this Parliament was with government against the abolition of the sinecure paymastership, 21 Feb. 1812, and on 28 May he was granted a month’s sick leave.
Vane Tempest was returned unopposed for the county in 1812, having given up a notion of standing for Antrim.
He died 1 Aug. 1813, leaving a daughter (later Lady Londonderry), who inherited his property and ‘immense fortune’ and, it was said, an illegitimate son ‘of whom he was very fond’.
