Yorke was again returned for Reigate in 1820 on the interest of his half-brother, the 3rd earl of Hardwicke. He was a fairly regular attender who continued to profess his support for Lord Liverpool’s ministry, but, being under no obligation to them since his swift exit from the admiralty in 1818, he displayed a marked streak of independence, particularly in his often irreverent interventions in debate. His chief concerns were for cost-effective naval defences, on which he freely offered ministers advice, and for general public economies. A naval biography of 1828, which was frank enough to admit that there were ‘differences of opinion’ about his professional worth, noted that while
his parliamentary speeches have not been remarkable either for length or profundity, they have been for a vein of facetiousness which has almost invariably run through them ... Though his speeches are generally off hand, he has the merit of seizing a strong point in debate, and placing it in so clear a light as to bring conviction to the plainest understanding.
J. Ralfe, Naval Biog. iii. 108-13.
His threat of a hostile vote on the civil list, 5 May 1820, proved to be an empty one. He tempered his ‘opposition speech’ for naval economies, 9 June, with praise for the comptroller of the service, Sir Thomas Byam Martin*. With a sneer at Elizabeth Fry, he condemned the penitentiary system and recommended transportation instead, 16 June; three days later he opposed the grant for the Millbank establishment. Though apparently favourable to mitigation of the penal code for shoplifters, 30 June, he wanted punishments to be specified. He denied that punishments at sea were unduly harsh, 13 July.
At the opening of the next session, 4 Feb. 1823, he initiated his practice of commenting on the address. He applauded ministers for adopting a neutral stance on the burgeoning conflict between France and Spain, but recognized that intervention might become inevitable. He was granted a fortnight’s leave for urgent private business, 12 Feb. His observations on the naval estimates were chiefly in their defence, 14 Mar., though he strongly disputed an assertion that the service was underfunded.
In welcoming the re-election of the speaker, Manners Sutton, 14 Nov., Yorke apparently made an unreported charge that James Brogden had used his position as chairman of ways and means to further his business interest; this was strongly denied, 21 Nov. 1826. That day he said he had hoped to find more ‘earnests of economy’ in the king’s speech, but Canning noted that he was one of those who voted against an amendment to it.
Yorke’s speech directly after the seconding of the address, 5 Feb. 1829, though dismissed as buffoonery by John Cam Hobhouse*, was important for its announcement that he would support Catholic emancipation.
In the autumn of 1830 the ministry listed him as one of the ‘good doubtfuls’. He had words of praise for the Speaker, 26 Oct. In lending his support to the address, 2 Nov., he described Lord Blandford’s amendment as ‘a tough and long yarn’ and turned his sarcasm on Wellington’s profligate nephew, William Pole Tylney Long Wellesley, while also warning of the possibility of revived French expansionism. One observer thought Yorke’s reply to these Members was ‘most complete’.
it cannot be denied that it must give a preponderating bias to that class, namely the £10 householder, which are by far the most numerous, active and republican class; who by living in towns, can be collected for any political purpose at a moment’s notice; who are shopkeepers, citizens, manufacturers, possessing great intelligence and spirit, and whose business it will be to have the chief government, and bring down the interests of the funds. This will, of course, straiten most severely all those who at present derive any income therefrom ... It will totally ruin a great many.
He was optimistic that the bill would be ‘greatly modified’, but continued to worry about the influence of the recent French revolution in all parts of Europe.
Yorke was returned again for Reigate at the subsequent general election, but did not live to take his seat. On 5 May 1831 he was aboard a small pleasure craft which sank with all hands in Southampton Water, off Netley Abbey, apparently after being struck by lightning. His sudden death was widely lamented: one obituarist, writing from an anti-reform perspective, mourned the passing of ‘a valuable ally to the cause of national freedom, and the menaced institutions of his native land’, while the Whig duke of Bedford observed that ‘he was, though eccentric and "rude in speech", a very good man’.
