Wigley, who went the Oxford circuit, owed his return for Worcester to an impulse of the independent freemen to unite in support of a respectable local man whose expenses they guaranteed. In 1790 he headed the poll. His new colleague Edmund Lechmere had hoped that Wigley might transfer his candidature to Leicester, of which he was recorder, but he had no such thought.
Wigley was counted hostile to repeal of the Test Act in Scotland in 1791. He upheld the prerogative right to deport aliens, 31 Dec. 1792, and opposed the Nottingham petition for parliamentary reform, 21 Feb. 1793. He foiled an attempt to impose a general limit on increases in canal tolls, 1 Mar. 1793. On 20 Feb. 1794 he championed provision for the families of militiamen. Defending legislation for the detention of conspirators, 16 May 1794, he was prepared to justify the proceedings against them at Leicester. He was in the minority against Pitt on the payment of the Prince of Wales’s debts, 1 June 1795. He supported the mixed bread bill, 18 Dec. 1795, and presented an apothecaries’ petition against the market in quack medicine, 23 Feb. 1796. The same day he opposed additional burdens to the county rates to meet legal costs, and unsuccessfully attempted to prevent the expulsion of John Fenton Cawthorne, 2 May 1796. Relying on Quaker votes at Worcester, he supported the bill to relieve them, 26 Apr. 1796, 17, 23 Feb. 1797.
Wigley was returned unopposed in 1796. Repeated applications to Pitt for a church living for his brother Edward had been disappointed.
Wigley was defeated by an unexpected third man at Worcester in 1802. He had relied on corporation and the dissenting leaders’ support, but he had neglected to keep a promise at the last election to treat his supporters to a feast. His friends thought his defeat was ‘effected by prejudices as groundless and unfounded as derogatory to the general character of the inhabitants of this city’.
