I share my hon. Friend's concern about empty properties, but will he have a word with his right hon. Friend the Secretary of State for Defence about the 13 per cent. of Ministry of Defence houses which are now empty, particularly in the area of Marchington in Staffordshire, where many such properties have been empty for four years? Will he ensure that the sound advice on housing management that is available in the Department of the Environment is conveyed to the Secretary of State for Defence?
