When a contest was threatened for Cambridgeshire at the approaching 1820 general election Manners advised his brother, the 5th duke of Rutland, on whose interest he sat, to withdraw him if it materialized.
Manners continued to support the Liverpool ministry, though he was an unenthusiastic politician and an indifferent attender, who was even keener than his brother, Member for Leicestershire, on hunting and riding. (He used a whip with an eyeglass fitted in the handle.)
A week before the 1826 general election Manners, anticipating ‘a very unpleasant day’ at best and an expensive contest at worst, advised Rutland to give up his interest in Cambridgeshire in the latter eventuality. A few days later, notwithstanding his awareness of their ‘very great unpopularity’ with some elements, he had come, as he told his brother, to
presume we must go to a poll, and I will go on until our committee recommend to give up. Believe me, I feel very little on my own account, for you must be aware that my personal ambition would never have led me to ask you to spend a farthing to get me returned for this county, or any other place whatever. I chiefly regret my situation on account of the additional harass[ment] and annoyance which this will cause your mind already overwhelmed with affliction [Rutland’s wife had died seven months earlier].
Rutland mss, Manners to Rutland, 16-19 June 1826.
At the nomination, he declared his support for undiminished agricultural protection and the existing constitution, ‘the envy of surrounding nations’. When asked by Samuel Wells, the radical Huntingdon attorney, if he would vote for reform, he ‘declined answering the question, as he considered it the business of a representative to be guided by the arguments which might be adduced when any question came under discussion’. After a diatribe against Manners, Rutland and their numerous family connections who held lucrative places, Wells nominated Henry Adeane*, a local squire, who had turned down a requisition to stand earlier that day. Even though Adeane declined the nomination and said he would vacate the seat if returned, his radical promoters forced a seven-day poll, principally to create trouble and expense for Rutland. They achieved that object, but posed no threat to the return of Manners who, polling mainly plumpers, finished at the head of the poll, almost 500 above Osborne.
He presented an anti-Catholic petition from the authorities of Ely cathedral, 5 Mar. 1827, and voted against relief the following day.
Manners attended the county meeting called to petition for repeal of the beer and malt taxes and revision of the licensing regulations, 23 Jan. 1830. Forced by clamour to speak, he as usual evaded the issue:
He was fully sensible of the existence of ... great distress ... and of the urgent necessity of applying some relief, if it could be effected without an infraction of the public credit. He should be ready to lay their petition before Parliament, but at the same time he should reserve to himself the privilege of fully examining every part of the question, and acting in that manner as he believed would best conduce to the interests of the country.
His obvious ‘mental reservation’ did not escape his critics, who secured the passage of a resolution instructing him and Osborne to promote the objects of the petition and a ‘general repeal of taxes’.
Adeane’s acceptance of a requisition to stand at the 1830 general election did not unduly alarm Manners who, ‘perfectly well in health, though still disabled in my arm’ (presumably after a riding accident), was initially confident of victory, though concerned over the likely cost.
At the general election of 1831 Manners, now backed by Hardwicke, was put up for Cambridgeshire as an opponent of the Grey ministry’s ‘wild and sweeping’ reform bill, a friend to ‘any safe and constitutional measure of reform’ and the champion of the agricultural interest. Even though Adeane, who had expressed reservations about details of the bill, seemed vulnerable, a week’s canvassing revealed that Manners had no chance, and he withdrew.
