Before the interlude in his parliamentary career which began in 1786 Dundas, who had been elected to Brooks’s in 1777, had opposed Pitt. His attempt to return to Parliament at a by-election for Berkshire in August 1794 coincided with the receipt of a peerage by his cousin and former political patron, Sir Thomas Dundas, as his share in the spoils of the Portland Whigs on their coalition with government, and there was confusion among local observers as to his current political views. Richard Benyon told Earl Fitzwilliam, 27 Aug., that Dundas was ‘supposed not to be so hostile to French principles as could be wished’ but, having heard that he was ‘supported by government’, concluded that ‘he has satisfied them that he is right in politics’; whereas Richard Aldworth Neville noted, 6 Sept., that he ‘professes himself an enemy to democracy’. Even Fitzwilliam was unsure of his ‘old friend’, as he told Benyon, 28 Aug.:
I don’t know, but I think we may be sanguine enough to hope, that he will support aristocracy when he gets into the House, whatever may appear to be his connexions without: however ... if there appeared anything in his professions... that leaned to Jacobinism, I should turn short upon him, and give him that for a reason.
At his unopposed election Dundas to some extent justified this uncertainty by avowing the ‘decided attachment’ to the existing constitution which present circumstances necessitated, but declaring himself in favour of an honourable and propitiously timed peace.
‘Although’, in his own words, he ‘had been disposed to vote in general with ministers’, Dundas supported Grey’s motion for peace negotiations, 26 Jan., also sided with opposition in favour of Sumner’s amendment concerning the Prince of Wales’s debts, 1 June, Fox’s call for peace, 29 Oct., and against the seditious meetings bill, 25 Nov. 1795, and was listed as ‘con’ by Rose in that year. He voted for the abolition of the slave trade, 15 Mar. 1796.
Despite claiming to be ‘almost tired of Parliament’, Dundas fought the contested election of 1796 with vigour and ‘found I had a strong support in many places from my being a friend to peace of which I am sorry to say there appears to be but a distant prospect’.
Dundas defended the volunteers against Windham’s attack, 10 Aug. 1803, but he supported the motions of Manners Sutton, 31 Mar. 1802, and Calcraft, 4 Mar. 1803, concerning the Prince of Wales’s finances and was classed by Rose in his list of early 1804 as a follower of Fox. He evidently took no part in the general attack on Addington, however, and in Rose’s list of May 1804 was reckoned an adherent of the fallen minister. Dundas’s opposition to the additional force bill in June led to his inclusion among the followers of Fox and Grenville in the list of September. He voted against government on the state of the defences, 21 Feb., and the repeal of the Additional Force Act, 6 Mar. 1805, but did not participate in the attack on Melville. On 22 Jan. 1806 he stated that had Sheridan not taken the matter up, he would himself have moved the repeal of the Additional Force Act, an ‘impracticable’ and ‘grievous, unfair and unjust’ measure; and he was teller for the majority in favour of the second reading of the repeal bill, 30 Apr. 1806. He assured Lord Howick, 3 Oct. 1806, that he was ‘a constant supporter’ of the ‘Talents’
Although Dundas voted consistently in opposition to government for the rest of the period, he declined to commit himself to a formal party allegiance. His attitude may be gauged from his refusal, despite his ‘complete approval’ of the scheme, to sign the requisition to Tierney in August 1818, when Lord Duncannon, showing no surprise, commented that Dundas objected only to signing his name to anything, and that he ‘never will attend party meetings’.
Dundas, who harboured no high political ambitions, and took pride in his self-consciously independent stance, was a diligent and respected private Member. He brought in a bill to facilitate the planting of potatoes in common land, 18 Mar. 1801, and was involved in the promotion of measures to regulate the sale of corn by weight, 26 Apr. 1796, and to strengthen the hand of magistrates in dealing with offenders, June 1804. His interests extended to reform of the Poor Laws (he sat on the committees of inquiry, 1817-19), electoral law reform, the amelioration of hardships caused by tax collection and the encouragement of inland navigation.
