As heir through his wife of the Morgans of Tredegar, Gould represented Breconshire, which was their preserve. Generally inclined to support administration, he had voted with his brother-in-law against Pitt over the Regency. By 1790 he was back on the government side, though his defection was not forgotten by Pitt, who did not seek his advice as a rule. He appears to have displayed little interest in national politics and rarely spoke in the House except on his business as judge advocate, but was always attentive to local interests and the needs of his constituents’.
Having in 1792 obtained possession of the Morgan estates, which commanded three seats in the House of Commons, Gould was transmogrified into Sir Charles Morgan, Bt., and stood in awe of his wealth. The Oracle newspaper cryptically reported on 3 July 1795: ‘Whoever looks for the chateau of Sir Charles G. M-g-n, one of the richest men in England, may repair to a room on the second floor of a little lodging house at Islington!’. On 3 June 1801 The Times reported that he would be made a peer. In 1806 he estimated his net income, apart from that of his son, at £11,000 a year. Yet he retained his office of judge advocate-general until then, despite an increase in court martial business as a result of the French wars and the union with Ireland, which he was not always competent to handle. Among his critics was the King.
Morgan left Parliament at the dissolution and died on 6 Dec. 1806.
