Treasury minister reveals some of the expected costs
The new Castle Rushen High School and sports complex is expected by the treasury minister to cost around £62 million.
Just over £3 million was allocated for the project in this year's Budget for the design and planning phase.
A 'masterplan' for the new site was unveiled in January, with the aim to have it completed by 2030.
Dr Alex Allinson has been responding to questions on this afternoon's Mannin Line.
He's been outlining some of the expected costs:
