Prior to the act receiving royal assent, Jack Lemley was appointed as chairman in 2005, but resigned on 18 October 2006.

Lemley was criticised by the government for breaking confidentiality, and Ken Livingstone suggested he had been treated more than fairly when asked to resign, being allowed a dignified departure due to his past services to the nation on the Channel Tunnel project and a generous compensation package.
