Of ‘old Whig principles’, Wrightson was generally a loyal supporter of the Liberal party following his return to the Commons in 1835.
Shortly after his return to Parliament in 1835, Wrightson was robbed on his way to the Commons of a petition which he was due to present from Northallerton’s licensed victuallers.
Wrightson’s enduring support for repeal of the corn laws – he had declared his opposition to them in his election address at Hull in 1830, and divided for Villiers’ motion that the corn law petitioners be heard at the bar of the House, 19 Feb. 1839
Wrightson was re-elected unopposed in 1847 and 1852, and saw off Conservative challenges in 1857 and 1859, albeit by very narrow margins. Having first been appointed to the select committee on standing orders prior to the 1847 election (although he did not attend its sittings that year), he was re-appointed to it annually for the remainder of his time in the Commons and was a regular attender.
Although an industrious committee member, Wrightson was not the most regular attender in the division lobbies, voting in 40 out of 219 divisions in the 1849 session, 55 out of 202 in 1853, and 43 out of 198 in 1856.
This interjection undoubtedly drew on Wrightson’s extensive experience as a magistrate, acting for many years as chairman of the Doncaster Quarter Sessions.
Wrightson canvassed Northallerton in 1865, but withdrew when it became apparent that his opponents were using corrupt methods against him. Jasper Johns, a wealthy London iron merchant, who stood in Wrightson’s place, successfully pursued a petition against the victorious Conservative, and then stood aside to allow Wrightson to contest the ensuing by-election, 11 May 1866.
