Meacher tabled a question in parliament last week “to ask the Secretary of State for the Home Department if she will set up a public inquiry into recent allegations that (a) the police and (b) the security services supplied information to the Consulting Association leading to the blacklisting of up to 3,200 building workers.”

The call follows revelations during a recent employment tribunal pursued by blacklisted worker Dave Smith.

Meacher also asked “if she will refer to the Director of Public Prosecutions for investigation and possible prosecution the 44 construction firms listed on the Consulting Association database as having used the services of that organisation to blacklist up to 3,200 building workers.”

Meacher is the second Labour MP to raise the issue after John McDonnell also called for a full public inquiry earlier this year.
