Cavendish, a veteran Rockingham Whig, continued to sit for Derbyshire on the family interest. A member of Brooks’s and an early member of the Whig Club (6 Dec. 1784), he was no longer active in the House. During the Regency crisis, he thought the Whigs were put at a disadvantage by ‘some misfortunes and perhaps some mismanagement’.
The perplexed situation of affairs I am clear is the consequence of the mistaken policy of this country, and if our rulers think that the only way to prevent the contagion that prevails abroad from spreading here to be force, they will bring on the same mischief here.
Soon afterwards he wrote that, in a situation requiring wisdom, ‘I am afraid we shall depend on nothing but cleverness’. He was listed a Portland Whig in December 1792, but the only further reference to his views, in January 1794, was to his hostility to the war with France.
He died 2 May 1794, aged 66, on his way back to London from Holker where he invariably kept Easter. ‘In him’, wrote Wraxall, ‘the hereditary probity of the Cavendish family, which in no individual of that line was more recognised ... supplied the place of ability.’
