Cranborne was returned on Lord Bruce’s interest at Great Bedwyn, and voted regularly with Administration. In 1780 Robinson noted in his survey: ‘Lord Cranborne will most likely be a peer very soon, and therefore desires to have only a temporary seat.’ He was returned at Launceston on the interest of the Duke of Northumberland, and at Plympton on Lord Edgcumbe’s interest, but almost immediately succeeded to the peerage. According to the Gentleman’s Magazine (1833, i. 564) he was ‘not ... remarkable for any active part in Parliament’, and his only recorded speech, 11 Feb. 1780, was against the Hertfordshire petition presented by William Plumer.1Almon, xvii. 91.
He died 13 June 1823.
- 1. Almon, xvii. 91.
