An intrepid officer, Spencer served three times in the West Indies in his first 20 years in the army, distinguishing himself in the Helder expedition (1799) and in Egypt (1801). After six years on the staff at home, during which he was a favourite royal equerry, he went on to serve at Copenhagen and in the Peninsula, where he was second in command to Wellington 1810-11. He had earned Wellington’s contempt for his unhelpful evidence in the Cintra inquiry and after being relieved in 1811 never again saw active service.

Spencer succeeded his brother Joshua as Member for Sligo in 1815 by arrangement with their nephew George Canning II*, purchaser of the seat, and held it until the dissolution when the agreement expired. Like his nephew and brother he supported government, apparently silently. Votes with ministers were reported on 8 May 1815, 18 Mar., 24 May and 20 June 1816, 25 Feb. 1817, and, after he had been invited to Fife House with other ministerially inclined Members, on 15 Apr. 1818. He died 29 Dec. 1828.
