Two proposals to scrap plans for the incinerator planned for Norfolk will be discussed by councillors at County Hall today.

Councillors will debate whether to pull out of the contract for the £596m plant, with a second motion calling for the government to step in to help the authority avoid a potential bill of millions of pounds.

Norfolk County Council's decision to award a contract to Cory Wheelabrator to run an incinerator in King's Lynn has been mired in controversy.

A vote over whether to pull out of the plant was secured after last month's elections, through a motion put forward by Conservative John Dobson, a long-standing opponent of the Saddlebow incinerator plan.

That vote is due to take place at a meeting of the county council today, against a backdrop of further controversy.

Council officers had said, should the council pull out of the contract it could cost as much as £90m, while if the secretary of state decides, following the public inquiry, not to ratify the authority's decision to award the plant planning permission, it could leave the council with a bill of nearer to £35m.

Those figures have been questioned and the cabinet last week ordered an independent review of the contract and the process which led to it being signed.

Anti-incinerator campaigners have been invited to play a role in picking a QC and a financial expert to run the rule over the contract, to see if they agree with what officers concluded.
