The National Government's huge majority left MacDonald with the largest mandate ever won by a British Prime Minister at a democratic election, but MacDonald had only a small following of National Labour men in Parliament. He was ageing rapidly, and was increasingly a figurehead. In control of domestic policy were Conservatives Stanley Baldwin as Lord President and Neville Chamberlain the chancellor of the exchequer, together with National Liberal Walter Runciman at the Board of Trade. MacDonald, Chamberlain and Runciman devised a compromise tariff policy, which stopped short of protectionism while ending free trade and, at the 1932 Ottawa Conference, cementing commercial relations within the Commonwealth.
