Labour-run Bolton Council sold land in Bolton town centre to Asons solicitors for just £1, it has emerged.
The special deal was set-up for the firm but plans to build a new office fell through.
The land was then sold back to the council and it was put back on sale at the full market rate.
Westhoughton town councillor David Wilkinson said: “Why was this solicitors firm given a special deal? It raises yet more suspicion over what Labour has been up to when it comes to using taxpayers’ money.”
The council went on to give the company a secret £300,000 grant, which has sparked fury across Bolton.
