One of the greatest mysteries surrounding the Circuit of Wales is exactly where the funding for the project is due to come from.

The ambitious project to build a circuit in the Blaenau Gwent region of South Wales will need some £325 million to complete it entirely, with around £200 million to come from private investors, the rest to come from public funds.

Though the Circuit of Wales has had plenty of headlines, there has been little word of any private investors putting any actual money into the project. That seems set to change.

Michael Carrick, Chief Executive of the Heads of the Valleys Development Company, the company behind the Circuit of Wales project, told the BBC that they have already raised £120 million in private investment, leaving £80 million still to find for development to go ahead.
