6th Duke of Rutland

Charles Cecil John Manners, 6th Duke of Rutland KG (16 May 1815 – 3 March 1888, in Belvoir Castle), styled Marquess of Granby before 1857, was an English Conservative politician.

Manners was the third but eldest surviving son of John Manners, 5th Duke of Rutland and Lady Elizabeth Howard, daughter of Frederick Howard, 5th Earl of Carlisle. John Manners, 7th Duke of Rutland and Lord George Manners were his younger brothers.He was educated at Eton and Trinity College, Cambridge, earning an MA in 1835.

Entering politics as Member of Parliament for Stamford in 1837, Manners became known as a voluble, if not particularly talented, protectionist. He briefly held office as a Lord of the Bedchamber to Prince Albert from 1843 to 1846. Following the resignation of Lord George Bentinck from the leadership of the protectionists in the House of Commons at the beginning of 1848, Granby (as he was then known) became leader on 10 February 1848, as Benjamin Disraeli was unacceptable to Lord Derby, the overall leader of the party, and the majority of the rank and file. Granby resigned on 4 March 1848, feeling himself inadequate to the post, and the party functioned without an actual leader in the Commons for the remainder of the parliamentary session.
