Morgan followed his father’s line in politics, and under George II supported Newcastle. He was absent from the divisions on the peace preliminaries. He opposed the Grenville Administration, and was connected with the Rockingham party at least until the end of the 1761 Parliament. His only known vote in the Parliament of 1768 was with Administration on the seating of Luttrell, 8 May 1769. Apparently he never spoke in the House.

Rockingham wrote to Lord Clive about the Morgan family on 17 May 1771:1

Within the last three or four years their conduct in Parliament has not been so favourable to what your Lordship and many of our friends might think right, and which was occasioned by their thinking themselves obliged by the honours of the lieutenancy and custos rotulorum of that county having been conferred upon them at a time when the Duke of Beaufort had made a point of having them.

And according to Walpole,2 Beaufort resigned his place of master of the horse to the Queen ‘because he could not wrench the lieutenancy of two Welsh counties from Morgan of Tredegar, the old Whig enemy of his house, and the more potent in Parliament’.

Thomas Morgan died on 15 May 1771.
