The official inquiry into the Edinburgh tram project is due to cost the same amount of money as Sir John Chilcot’s investigation into the Iraq war, a newly-obtained document has revealed.

The Edinburgh Tram Inquiry will have cost the public purse £13,100,812 by the end of this financial year, the detailed projection provided by Transport Scotland showed.

This is almost an identical sum to the Iraq Inquiry, which, according to its own most recent estimate, had cost £13,126,900 by the time it published its 12-volume report in 2016.
