'Deep concerns' have been raised by a National Assembly committee over the Welsh Government's approach to the Circuit of Wales.
In accepting government ministers were right to consider supporting the building of a new race track near Ebbw Vale, the Public Accounts Committee concluded officials made inexplicable decisions in providing funding for the project, and failed to keep the then Minister for Business, Enterprise, Technology and Science up to date with latest developments.
Its report says, in total, more than £9 million of public money was spent on the Circuit of Wales by the Welsh Government before it ended its involvement, after refusing to act as guarantor for £210 million in loans - almost half the total cost of the project.
The Committee found that there were a number of errors in the communication from Welsh Government officials to the public over the purchase of a motorcycle company in Buckinghamshire by the Heads of the Valleys Development Company (HoVDC), the company responsible for delivering the project.
The Welsh Government said there were lessons to be learnt.
