A Tory nominee of the Rutland interest, Manners, who was ‘an excellent horseman’, had sat for Cambridgeshire, where his family possessed extensive landholdings, with the support of his brother, John Henry Manners (1778-1857), 5th duke of Rutland, from 1802-1830.
In late 1835 Manners filled the vacancy for North Leicestershire, in which the family seat, Belvoir Castle, was situated, after the sudden death of his brother, Lord Robert, who was also a soldier, huntsman and indifferent parliamentarian. After expressing his ‘fear and apprehension’ about the Whigs’ Irish policy, Manners was returned unopposed.
In Parliament, Manners supported the new poor law, but unlike other Leicestershire MPs, such as Edward Basil Farnham or Henry Halford, he did not favour weakening the Commission. He remained committed to agricultural protection, and at the 1841 general election, at which he was again returned unopposed, he argued that a graduated scale of duties was the ‘fairest and most impartial arrangement’ for producers and consumers, and he supported Peel’s revised corn law of the following year.
Manners, who was always a lax attender, resisted the repeal of the navigation laws, 12 Mar. 1849, and supported Disraeli’s motions to relieve agriculture, 15 Mar. 1849, 13 Feb. 1851, before retiring at the 1852 general election, when he was replaced by his nephew, Charles Cecil John Manners, marquis of Granby (1815-88).
