§ Mr. Edward Davey
To ask the Deputy Prime Minister what assessment he has made of the efficacy of his definition of(a) previously developed land and (b) brownfield sites; and what plans he has to alter that definition. 
§ Mr. McNulty
There are a number of definitions in use. The technical agreement for the Department of Environment, Transport and Regions public service agreement 2001– 04 defined previously-developed land (PDL) by reference to the definition of PDL in planning policy guidance note 3 housing (PPG3) and brownfield land as all land included in the National Land Use database (NLUD-PDL). The practical application of the definition of PDL is kept under review by the NLUD Board and has been considered in the course of ongoing research on the implementation of PPG3. There are no plans to alter the definition.
