Query: When was the Wye College campus closed?
Context: One commentator observed that Imperial's scheme reflected "the state of democracy in Kent, the transformation of a renowned scientific college into a grasping, highly aggressive, neo-corporate institution, and the defence of the status of an Area of Outstanding Natural Beauty – throughout England, not just Wye – against rampant greed backed by the connivance of two important local authorities. Wye College campus was finally closed in September 2009.
