Legal wrangle report goes to cabinet

The report into the NNDC agreement with Tesco goes to the cabinet today although we don't get to see it until the end of June. The report is expected to conclude that the council's executive committee gave authority for the signing of the deal. In a statement the council said the agreement did not involve planning officers or the planning committee. But the BBC has been told an officer, with the authority of senior councillors, signed the agreement with Tesco. What we need to know now is why? and is it legal?
