With the life of his grandfather in the balance, it was touch and go whether Dundas would once again come in for the family’s nomination borough of Richmond in 1820 or try to fill his father’s shoes by contesting York. In the event, his grandfather’s health rallied and Dundas remained at Richmond.
He divided for Catholic relief, 6 Mar. 1827. He voted for inquiry into Leicester corporation, 15 Mar., information on the mutiny at Barrackpoor, 22 Mar., and the spring guns bill, 23 Mar. He divided against Canning’s coalition ministry for the disfranchisement of Penryn, 28 May 1827. That December he received a request to attend at the opening of the next session from Lushington, the Goderich ministry’s patronage secretary.
The ministry naturally regarded him as one of their ‘foes’, and he voted against them in the crucial division on the civil list, 15 Nov. 1830. When presenting a York anti-slavery petition, 12 Nov., he noted that ‘the petitioners state that they would submit to any sacrifice for the purpose of having it abolished’, and remarked that ‘I wish everyone would do the same’. He presented and ‘cordially’ concurred in a York petition for repeal of the assessed taxes, 10 Feb. 1831. In presenting a corporation petition in favour of parliamentary reform, 16 Mar., he promised to give his ‘earnest and cordial support’ to the Grey ministry’s bill; he divided for the second reading, 22 Mar. While accepting that some of the York freemen objected to their proposed disfranchisement, 30 Mar., he maintained that the bill had ‘on the whole ... received the cordial support of the majority of my constituents, who are willing to sacrifice their own interests for the sake of carrying the measure unimpaired’. He voted against Gascoyne’s wrecking amendment, 19 Apr. 1831. He stood again for York at the ensuing general election, when he declared that ‘effectual reform in the representation of the people was essential to the welfare and security of the state’ and insisted that ‘the objections raised to the measure were feeble’. He was returned unopposed with his Tory colleague.
Dundas offered again for York at the general election of 1832 but came bottom of the poll. He filled a vacancy in the borough’s representation in September 1833, but returned to Richmond in 1835 and remained there until he succeeded to his father’s earldom in February 1839. He was an enthusiastic supporter of the Turf and a prominent freemason, becoming grand master of England in 1843.
