the Soviet Union had a non-aggression pact with Germany, the Daily Worker ceased to attack Nazi Germany. On 21 January 1941, publication of the newspaper was suppressed by the Home Secretary in the wartime coalition, Herbert Morrison (a Labour Party MP). It had repeatedly ignored a July 1940 warning that its pacifist line contravened Defence Regulation 2D, which made it an offence to 'systematically to publish matter calculated to foment opposition to the prosecution of the war'. A Scottish edition of the Daily Worker was produced from its plant in Glasgow from 11 November 1940. On 16 April 1941, the Daily Worker offices at Cayton Street were totally destroyed by fire during the Blitz. The paper moved temporarily in 1942 to the former Caledonian Press offices in Swinton Street (whence the old Communist Party Sunday Worker, edited by William Paul and Tom Wintringham, had been published from 15 March 1925 until 1929). New offices were acquired in 1945, at a former brush-makers' warehouse at 75 Farringdon Road, for the sum of £48,000. When Germany invaded the Soviet Union in Operation Barbarossa in June 1941, the situation changed; British Communists became fervent supporters of the war. For the rest of the war, the paper was a strong supporter of the British war effort, and campaigned to organise a "Second Front" in Europe to assist the Soviet Union. The government's ban on the Daily Worker was lifted in September 1942, following a campaign supported by Hewlett Johnson, the Dean of Canterbury, and Professor J. B. S. Haldane. A "Lift the ban" conference at Central Hall, Westminster on 21 March 1942 was attended by over 2,000 delegates. A key part of the campaign was to secure Labour Party support (Herbert Morrison was a fierce opponent of the Daily Worker). On 26 May 1942, after a heated debate, the Labour Party carried a resolution declaring the Government must lift the ban on the Daily Worker. The Daily Worker welcomed the dropping of the atomic bomb on Hiroshima, editorialising "The employment of the new weapon on a substantial scale should expedite the surrender of Japan". The paper also applauded the bombing of Nagasaki, and called for the use of additional atomic bombs against the Japanese. The People's Press Printing Society was formed just after the war in 1945. The Society's purpose was to raise money for the paper under a co-operative ownership model, and it
