Erskine’s early career was directed by his uncle Alexander Wedderburn who lost no opportunity of advancing the interests of his sister and her children. When in 1779 Wedderburn was raising demands against Government, he extracted from North a promise of a reversion for his nephew.
In the new Parliament Erskine made his mark as a forceful Opposition speaker. He intervened in the Westminster election debate, 8 June 1784; spoke on the military and financial provisions of the East India bill; and warmly defended Fox against Pitt.
Sir James Erskine is at present in Holland but I saw him at Newcastle, and I think nothing can have happened to alter the disposition he then had to disengage himself entirely from his contest in Scotland. It will always be my wish that he should think of Morpeth only, while you are so good as to think of him for that place ... For supposing his success in Scotland could be ensured, I am satisfied it would be better for his fortune and his constitution and his political situation even to fight Morpeth under your auspices ... than to take the charge and burthen of a large county with all its claims upon him. My former adoption of that project was entirely from complaisance to his cousin who wished to support a family interest without being at the trouble of it.
In the new session he was almost wholly engrossed in East India affairs, was a teller in the division, 11 Dec., on Fox’s motion to add Francis to the managers of Hastings’s impeachment, and was nominated a manager in the impeachment of Sir Elijah Impey. With an eye to his Fife interest he intervened occasionally on Scottish affairs; spoke on the distillery bill, 12 Feb. 1788, and opposed on 17 June Sheridan’s motion for a bill to reform Scottish burghs, ‘strongly protesting against the existence of the evils complained of’. During the Regency debates he spoke at least twice.
He died 18 Jan. 1837.
