O'Sullivan vows inquiry 'if planning process shows hint of corruption'

The Planning Minister Jan O'Sullivan has said she will order an external investigation if there is a hint of corruption in files under review in the Department of the Environment.

Ms O'Sullivan has again denied the Coalition is trying to suppress inquiries at a number of local authorities.

The files are being reviewed in the Department after no progress was made since John Gormley announced inquiries in June 2010.

Minister O'Sullivan has said there will not be any cover-up.
