The official investigation into the Edinburgh tram project is set to exceed £13m by the end of this financial year.
The vast majority will be spent on staff costs, which are due to reach £6.1m while legal fees are projected to hit £3m.
A further £1.38m is expected to have been spent on IT system costs, as well as £868,859 on rent for office facilities and £419,928 on the inquiry’s media team.
