Eyre, ‘a plain country gentleman’, was a potential candidate for his county on the death of Evelyn Pierrepont in 1801, but Pierrepont’s brother than succeeded. On the next vacancy, made by Lord William Henry Cavendish Bentinck, he was returned unopposed.
Could you inspire your new colleagues with the same principles which actuated your late administration, and which prompted you not to lose sight of economy in the midst of the most vigorous exertions, and to reject some measures apparently more efficient rather than infringe the constitution, in the purity of which consists our greatest strength, the government will be zealously supported by the country at large and may defy any combination of parties which may be formed against [it].

He voted for the criminal prosecution of Melville, 12 June, and in July 1805 was again classed as a doubtful follower of Sidmouth.
Eyre voted for the repeal of Pitt’s Additional Force Act, 30 Apr. 1806, announcing on 13 May that it had failed; but on 26 June and 3 July he criticized Windham’s training bill as too severe and likely to destroy the volunteer system. At that time the 4th Duke of Newcastle threatened to oppose Eyre’s re-election for the county (his colleague was by then his own son-in-law), but he refused to yield to threats, not being conscious of any dissatisfaction with his conduct, so he informed Newcastle, 18 July. He was not opposed.
Eyre supported the Portland ministry. He warned the landed interest against ‘false alarm’ about the prohibition of distillation from grain in a speech in favour of sugar distillation, 3 June 1808. He failed to secure election to the finance committee in 1809. He rallied to Perceval’s ministry on the address, 23 Jan. 1810, and even when he admitted that he could not vote with them on 26 Jan., said their ‘merit was not sufficiently understood by the country’. Laughed at for this, he rallied to them again on the further Scheldt questions of 23 Feb. and 30 Mar. He was listed ‘doubtful’ from the Whig standpoint. He went on to vote against the release of the radical detainee Gale Jones and against parliamentary reform, 16 Apr., 21 May. He was in the ministerial minority on the Regency question of 1 Jan. 1811. In March his only son was slain at Barossa. On 14 Feb. 1812 he seconded the introduction of anti-Luddite legislation and went on to defend it. Writing to Bryan Cooke about the debate of 27 Feb. he was disillusioned about the Regency and critical of the airing of the issue of Catholic relief.
Eyre retired from Parliament in 1812, but remained active as a county magistrate. He died 13 Apr. 1836.
