asked the Minister of Housing and Local Government whether he will give separate percentage figures for dwellings at present under construction for local authorities and owner-occupiers, respectively, which are employing industrialised building methods.

On 30th September, 1965, 17·8 per cent. of dwellings under construction for local authorities and new towns in England and Wales were being built by industrialised methods. My right hon. Friend has no comparable figures for the private sector, but the numbers are very small.
