Carillion have been told that they are no longer welcome at the Labour Party Conference next week after members of its National Executive Committee highlighted the firms blacklisting history.
Their stand will be replaced by a "GMB Blacklisting Information" stand.
Their Chief Executive, Richard Howson continues to insist that their involvement was limited to a subsidiary, Crown House.
This is simply not true.
I named senior Carillion (previously Tarmac) managers and their HR Director, Frank Duggan in my evidence to the select committee which can be viewed here.
