At the 1929 general election, he and Tommy Lewis were elected as the first Labour MPs for the two-seat Southampton constituency. They both lost their seat at the 1931 general election, having been among the Labour MPs who refused to follow the Prime Minister and Labour Party Leader Ramsay MacDonald into a coalition with the Conservatives to form the National Government. Morley and Lewis returned to the House of Commons in the Labour landslide at the 1945 general election.
When the two-seat Southampton constituency was divided at the 1950 general election, Morley was returned for the new Southampton Itchen constituency, which he represented until his death shortly before the 1955 general election.
Before and during World World War II, Morley taught at Sholing Boys" School, Southampton. He is commemorated in local schools by the Ralph Morley Essay Competition.
