In 1928 Bevan won a seat on Monmouthshire County Council. With that success he was picked as the Labour Party candidate for
Ebbw Vale (displacing the sitting MP), and easily held the seat at the
1929 General Election. In Parliament he soon became noticed as a harsh critic of those he felt opposed the working man. His targets included the Conservative
Winston Churchill and the Liberal
Lloyd George, as well as
Ramsay MacDonald and
Margaret Bondfield from his own Labour party (he targeted the latter for her unwillingness to increase unemployment benefits). He had solid support from his constituency, being one of the few Labour MPs to be unopposed in the
1931 General Election.
Not long after he entered parliament Bevan was briefly attracted to
Oswald Mosley's arguments, in the context of Macdonald's government's incompetent handling of rising unemployment. However, in the words of his biographer John Campbell, "he breached with Mosley as soon as Mosley breached with the Labour Party". This is symptomatic of his lifelong commitment to the
Labour Party which was a result of his firm belief that only a Party supported by the
British Labour Movement could have a realistic chance of attaining political power for the
working class. Thus, for Bevan, joining Mosley's
New Party was not an option. Bevan is said to have predicted that Mosley would end up as a
Fascist.
He married fellow socialist MP
Jennie Lee in 1934. He was an early supporter of the socialists in
Spain and visited the country in the 1930s. In 1936 he joined the board of the new socialist newspaper the
Tribune. His agitations for a united socialist front of all parties of the left (including the
Communist Party of Great Britain) led to his brief expulsion from the Labour Party in March to November 1939 (along with
Stafford Cripps and Trevelyan). However, he was readmitted in November 1939 after agreeing "to refrain from conducting or taking part in campaigns in opposition to the declared policy of the Party."
He was a strong critic of the policies of
Neville Chamberlain, arguing that his old enemy
Winston Churchill should be given power. During the war he was one of the main leaders of the left in the Commons, opposing the wartime Coalition government. Bevan opposed the heavy
censorship imposed on
radio and
newspapers and wartime
Defence Regulation 18B, which is gaven the Home Secretary the powers to intern citizens without trial. Bevan called for the
nationalisation of the coal industry and advocated the opening of a Second Front in Western Europe in order to help the
Soviet Union in its fight with
Germany. Churchill responded by calling Bevan "... a squalid nuisance".
Bevan believed that the
Second World War would give Britain the opportunity to create "a new society". He often quoted an 1855 passage from Karl Marx: "The redeeming feature of war is that it puts a nation to the test. As exposure to the atmosphere reduces all mummies to instant dissolution, so war passes supreme judgment upon social systems that have outlived their vitality." At the beginning of the
1945 general election campaign Bevan told his audience: "We have been the dreamers, we have been the sufferers, now we are the builders. We enter this campaign at this general election, not merely to get rid of the Tory majority. We want the complete political extinction of the Tory Party."
After World War II, when the
Communists took control of
China. Parliament debated the merits of recognizing the Communist government. Churchill, no friend of Bevan or
Mao Tse-Tung, commented that recognition would be advantageous to the United Kingdom for various reasons and added, "Just becaus you recognize someone does not mean you like him. We all, for example, recognize the Right Honorable Member from Ebbw Vale."
