Lawley, as he was first known, was named after his maternal great-grandfather, Beilby Thompson (d. 1750), and great-uncle (1742-99), Member for Hedon and Thirsk, whose Yorkshire estates, worth almost £16,000 a year in 1813, he inherited in 1820 on the death of his uncle Richard Thompson, whose name he then took.
I have long from the papers been informed of your attempt upon Wenlock and of its result; and I am sorry to say that I cannot afford you my approbation upon that subject. You have no right to avail yourself of your accidental residence upon that estate to procure to yourself any personal advantage unless it is yours, or without the express approbation of myself and of Francis, whom it appears you have not consulted in the business.

He nevertheless offered his future assistance, provided ‘you determine to pursue patriotic and independent principles in Parliament’.
Thompson, a silent Member, who acted in opposition to the Weld Foresters, and apparently independently of the Williams Wynns, cast his few known votes with his brother Francis, who since coming in for Warwickshire in November 1820 had divided steadily with the Whig moderates.
Ministers counted Thompson among their ‘foes’, but he was absent from the division on the civil list which brought them down, 15 Nov. 1830. He was granted a fortnight’s leave on urgent private business after sitting on an election committee, 14 Feb. 1831, and another week on account of ill health, 11 Mar. He divided for the Grey ministry’s reform bill at its second reading, 22 Mar., and against Gascoyne’s wrecking amendment, 19 Apr. 1831. His return at the general election that month was unopposed.
Despite their differences with the Williams Wynns on reform, the Thompsons remained regular guests at Wynnstay, and acted as political advisers to Caroline Thompson’s nephews Henry and Sir Stephen Glynne when they came in for Flint Boroughs as reformers in 1831-2.
Thompson was admitted to Brooks’s, 26 July 1834, and remained a lifelong Liberal, although he opposed them over the appropriation of Irish church revenues in 1836. He lost his seat in 1837, and in 1839 was created Baron Wenlock, which title had been in abeyance since his brother’s death without issue in 1834, and was of no interest to Francis (d. 1851), whose heir in the baronetcy he remained.
