Vane, who succeeded to his father’s baronetcy less than a month after its creation, replaced his kinsman Viscount Barnard at Winchelsea when he was called to the Upper House as 3rd Earl of Darlington in 1792. He was excused from attending the House on 4 Mar. 1793 ‘on account of the ill state of his health’,
In 1796 Vane replaced Wilson Braddyll as the partner of John Christian Curwen in the anti-Lowther interest at Carlisle, where he survived a long and expensive contest and a petition against his return. Having been proposed by Fox, he was elected to Brooks’s on 30 Oct. 1796,
Vane, who was one of Brougham’s ‘stoutest supporters’ in his attack on the Lowthers in Westmorland in 1818, unsuccessfully stood against the Lowther interest at Cockermouth and was only restrained by Brougham from supporting Curwen against Viscount Morpeth in Cumberland. He signed the requisition for a Cumberland county meeting in October 1819 to consider Peterloo and wrote to Brougham on 30 Sept.:
I made this addition opposite my name, ‘and also to consider of the necessity of a reform in Parliament’. If that question is not brought forward, it might appear that a change of ministers was our only object, but I suppose most of us will be of opinion that no change can be of much use without a reform in the borough system.
Add. 51561, Brougham to Holland, 28 June; 51565, same to Lady Holland, 25 June 1818; Brougham mss 27490.
He died in March 1832.
