§ Mr. Matthew Taylor
To ask the Secretary of State for the Environment what research he has commissioned or evaluated into the Mundic problem with special reference to houses in Cornwall. 
§ Mr. Clappison
The Department funds a continuing research programme at the Building Research Establishment, with industry support, into these problems.
This work has led directly to the publication of revised guidance from the Mundic committee of the Royal Institution of Chartered Surveyors. The application of which has resulted in an estimated 70 per cent of previously blighted properties now being classified as suitable for lending purposes.
