During the Second World 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 gave the Home Secretary the powers to intern citizens. Bevan called for the nationalisation of the coal industry and advocated the opening of a Second Front in Western Europe to help the Soviet Union in its fight with Germany. In one of his most noted speeches made against Churchill, he railed that the prime minister "wins debate after debate and loses battle after battle". Churchill would later label Bevan "a squalid nuisance". Churchill was a frequent target of Bevan's, who already held a dislike of him following his intervention in the Tonypandy riots and the 1926 United Kingdom general strike which Bevan considered heavy handed. Bevan believed that the key to the war was the involvement of Russia and considered Churchill was too focused on the intervention of the United States. Bevan also feared that allowing Churchill to continue unopposed and unchallenged in Parliament during the war would leave him almost unbeatable for the Labour Party in future elections. Historian Max Hastings described Bevan's role in Parliament during the war as "his figures were accurate but his scorn was at odds with the spirit of the moment—full of gratitude, as was the prime minister". His fierce opposition made him unpopular with some portions of the public at the time, his wife later described how the couple would frequently receive parcels filled with excrement at their home.
