Gunning’s family were originally from Cornwall, but his grandfather, a career diplomat, was created a baronet and purchased Horton in 1778. His father, Member for Wigan, 1800-2, Hastings, 1802-6, and East Grinstead, 1812-18, was a steady friend of the Liverpool ministry and had been expected to come in for one of Lord Bath’s seats at the 1820 general election, but was passed over.
At the 1830 general election Gunning offered again for Northampton as a supporter of the Wellington ministry. Pressed for his views on parliamentary reform, he declared that he had ‘always been equally reluctant blindly to support antiquated institutions, or rashly to depart from the system of our ancestors’, and that he would only support gradual and moderate change, for example the transfer of seats from places where the ‘elective franchise has been grossly abused’ to ‘some large unrepresented town’. After another fierce contest he was returned in second place, but because of his poor health his brother Henry was chaired in his stead.
At the ensuing general election he offered again, insisting that the question at issue was not ‘reform or no reform’, but the specific ministerial bill. On the hustings he reiterated his pledge to support a degree of reform, complained that the people had lost sight of the ‘beauties and excellencies’ of the existing representative system, and protested at the proposed reduction of English Members and increase of Irish. After coming third in the poll he demanded a scrutiny, which lasted 15 days, but did not alter the result.
In the event Gunning did not seek election again. He had been named as sheriff of Northamptonshire in 1825, but declined to serve.
