He was elected at the 1922 general election as Member of Parliament (MP) for Stratford division of West Ham, and held the seat until 1945. He had wanted to stand again at the 1945 general election, but his name was not sent on to the selection conference which chose Henry Nicholls as the Labour Party candidate. Groves announced that his son would stand as an independent candidate, but when his son withdrew he stood for re-election, and was promptly expelled from his local Labour Party.
