The posts by Ashley Cain, albeit from many years ago, are completely unacceptable. The BBC has clear requirements around vetting and social media checks, which are undertaken by the production company. In this instance, the process clearly failed and we are investigating why. We are continuing to strengthen our processes to ensure everyone working for, and on behalf of, the BBC meets our values and standards. We have no plans to broadcast the new series of 'Into the Danger Zone', and have no future projects with Ashley Cain.
