A draft of the revised PPS6, which sets out the government's policy on town centre and retail development, will be released before the end of September. Under the proposals: Out goes the needs test, the 'blunt instrument' that allows planners to reject schemes if an area's 'need' is deemed to already have been satisfied The impact test, which monitors the effect of new stores on the vitality of town centres, will be strengthened The sequential test, which forces retailers to choose central sites over out-of-town locations, will remain, but could be made more flexible to encourage more town centre development The planning system as a whole will be made to take more account of the economic benefits of development
