Trade Disputes 24. Sir John Mellor asked the Minister of Labour what trade disputes have been reported to him in connection with the Festival of Britain preparations during the past six months; how many men were involved; and for how many days. Mr. Lee During the six months ended March, 1951, four stoppages of work arising from industrial disputes at the Lambeth or Battersea Festival of Britain sites have been reported to my Department, and a fifth stoppage was reported in connection with Festival of Britain work at the Science Museum, Kensington. The aggregate number of workers involved in these five stoppages was about 1,450 and the aggregate time lost was about 3,500 working days.
