 While he was an MP Noel-Baker advocated reforms to moderate the influence of outside interests in Parliament.In 1961 he published an article in "Parliamentary Affairs" warning that "the door, in fact, is wide open for a new form of political corruption, and there is an uneasy feeling in Parliament and outside that its extent could be much greater than the known or published facts reveal".Before his death in 2009 Noel-Baker was one of the few surviving members of the 1945 Parliament, the others being Michael Foot and John Freeman.
