Returned for Grantham on the Rutland interest in 1741 while still in Turkey,1 Granby was absent from all the recorded divisions of his first Parliament, except that of 18 Jan. 1744 on the Hanoverians, in which he voted against the Government. During the Forty-five he served in Scotland as colonel of a regiment raised by his brother, the Duke of Rutland, retaining his rank when the regiment was disbanded. He was classed as ‘doubtful’ in 1746 but as ‘opposition’ at the opening of the 1747 Parliament. At this time his reputation was that of a racing man and a gambler already deep in debt.2 When pressed by the Pelhams in 1752 to gain ‘the great and extensive interest of the Rutland family’ by giving Granby the Blue Regiment (the Royal Horse Guards), George II flatly refused, referring to him as ‘a sot, a bully, that does nothing but drink and quarrel, a brute’.3

He died 18 Oct. 1770.
