Stewart, who owed much to the 1st marquess of Abercorn, no doubt a distant cousin of his mother, retired as an Irish law officer in 1803 in exchange for a baronetcy and a pension. Returned for his native county on the Abercorn interest, 1802-6, and again, with the assistance of Lord Belmore, from 1812, he usually supported the Liverpool administration and, as an Orangeman, opposed Catholic relief.
Remarking that ‘many of the most loyal inhabitants of that country felt sore’ regarding the legal proceedings in Ireland against the Orange rioters, Stewart hinted that he would raise the matter again, 18 Feb. 1823.
