I would refer the hon. Member to paragraph 9 of the Explanatory Memorandum on the Concentration of Production (Cmd. 6258). It is there stated that one of the conditions which a nucleus firm must satisfy is that it must provide for the plant of the closed firm to be kept intact, unless the premises should be requisitioned. A register of firms who are parties to concentration arrangements is being kept, and the Government departments concerned will take all measures open to them to assist the speedy reopening after the war of firms closed as a result of these arrangements.
