I am shocked and appalled by the results of an internal police investigation, the Creedon report, which revealed the illegal treatment of construction workers by the major British building firms and the police.

The names of construction workers were kept on a blacklist that led to them being refused work or fired from employment. Workers were blacklisted for activities such as joining a trade union, campaigning for safe conditions and even asking for clean toilets.

We need an inquiry into the blacklisting scandal which destroyed lives, families and reputations for decades, and we demand justice for those affected.
