HC Deb 08 April 1970 vol 799 c93W
Mr. Hugh Jenkins

asked the Minister of Housing and Local Government whether the National Building Agency took into consideration the risks of a Ronan Point type explosion in relation to prefabricated system-built units.

Mr. Freeson

The Tribunal of Inquiry found that none of the bodies concerned was fully cognisant of the possible extent of progressive collapse following an explosion of the Ronan Point type.
