Protesters stormed the South London Waste Partnership (SLWP) committee meeting this evening enraged that accidentally leaked documents suggest a larger and noisier incinerator than previously thought could be built in Sutton.

Kingston Council accidentally published 100 pages of restricted material that showed contractor Viridor was not happy with its planning permission restrictions at the proposed site in Beddington Lane, Sutton.

Councillors allowed 10 minutes of public questions at the meeting but would not answer any queries about the incinerator project or other material in the restricted pages.

The meeting at Croydon Town Hall lasted only 25 minutes before the public were asked to leave so that members of Merton, Sutton, Kingston and Croydon councils could discuss the confidential documents.

David Pettener, who has been protesting the proposed incinerator for six years, was the only member of the public allowed to ask questions of the committee.

However when he tried to ask about the leaked documents chair councillor Judy Saunders said that the committee would not be answering anything that was not on the official agenda.

Mr Pettener said: “How can I not have my questions answered in a public meeting?

“The bulk of this meeting is being held behind closed doors. These people are supposed to be public officers and we are not being allowed to hold them to account."
