 Not a regular speaker in the House, Watts Morgan busied himself with work on various committees, dealing mainly with gas, electricity, river pollution, the Home Office and the Police Council. Despite his work on private bills and his friendly relationship with Prime Minister Ramsay MacDonald he was never considered for office. In the 1922 election, Watts Morgan was forced to contest his seat for the first time when he was challenged by Frederick William Heale. Watts Morgan made it clear that he would defend the interests of ex-servicemen and those injured in industry; he opposed the temperance demand for the local veto. It was a close result for a Rhondda election; Heale lost by just over 3,000 votes. The 1923 election was a different affair, with Watts Morgan defeating Conservative candidate Alfred John Orchard by nearly 13,000 votes.
