later won a seat at West Fife in the 1935 general election to become the only Communist Party of Great Britain MP to sit in the House of Commons. Formerly a Liberal Party stronghold, the industrial districts switched to the Labour Party by 1922, with a base among the Irish Catholic working class districts. Women were especially active, with solidarity on housing issues. However, the "Reds" operated within Labour and had little influence in the British Parliament. The mood therefore changed to passive despair by the late 1920s. Decline of industry and the post-war period Glasgow did not escape the effects of the Great Depression. Second World War The outbreak of the Second World War in 1939 temporarily arrested the ongoing decline, with the city's shipyards and heavy industries working at capacity to fuel the war effort, but this too came at a price — the Luftwaffe bombing of Clydeside (the worst of which was the Clydebank Blitz in March 1941 (although the target of the bombing, the shipbuilding town of Clydebank, is just outside Glasgow itself). Deindustrialization Although ships and trains were still being built on Clydeside, cheap labour abroad reduced the competitiveness of Glasgow's industries. New shipbuilding superpowers such as Japan began to emerge as the competitiveness of the Glasgow shipyards began to decline. The major shipbuilders on the Clyde began to close down, but not before Clydebank had built one of its last great ships, Cunard's Queen Elizabeth 2. As of today, three major shipyards remain on the River Clyde, two of which are owned by BAE Systems Naval Ships; Govan and Scotstoun, which focus principally upon the design and construction of technologically advanced warships for the Royal Navy and other navies. Glasgow's function as a port also diminished - the introduction of containerized freight spelled the end for the riverside's docks and wharves which had crumbled into dereliction by the late '60s. Regeneration As WW2 came to a close, the chief engineer of Glasgow Corporation - Robert Bruce - published the first of two highly influential studies into how the city could be regenerated in the future without the dominant heavy industries which had brought it much wealth in the past. The Bruce Report, as it would become known, would ultimately become the blueprint of the Glasgow of today. Its basic aim was to depopulate the overcrowded centre, dispersing the population to outer areas of the
