Loughborough’s great-uncle Alexander Wedderburn†, 1st earl of Rosslyn, was lord chancellor under Pitt. When he died in 1805 his peerage and half of his estates passed to his nephew, this Member’s father, Sir James St. Clair Erskine. A career soldier and a Whig (as was his wife (d. 1810), a granddaughter of the 1st Viscount Folkestone), from 1796 until his removal to the Upper House he represented Dysart Burghs, where, in alliance with his partisan William Ferguson of Raith, he established a controlling interest. From 1806, he grudgingly acquiesced in the return there of Ferguson’s second son Ronald Craufurd Ferguson.
Ministers of course listed Loughborough among their ‘friends’, but he was one of four sons of peers in the cabinet, with seats in the Commons, who, although in town, failed to speak or vote with government on the civil list when they were brought down, 15 Nov. 1830.
Loughborough was not without a seat for long. In August 1831 he successfully contested Great Grimsby, where the return of two Tories at the general election had been voided, with his partisan Henry Fitzroy. On the hustings he said it was evident that the reform bill would pass the Commons, but it was in the Lords, where his father sat, that the real struggle would be made, and they might ‘fairly hope to obtain a reversion of the case of Grimsby’, which was set to lose a Member. He claimed that he was not opposed to all reform but ‘decidedly hostile’ to the ministerial bill.
Loughborough announced his candidature for Grimsby as a Conservative, 3 Oct. 1832, before joining his regiment in Ireland, but, as he had anticipated, he faced powerful opposition and was defeated at the general election in December.
