THE Greens pose a “serious threat” to Labour’s historic reputation as the party for working people, top Green trade unionists said yesterday.

RMT president Peter Pinkney, who revealed he was standing for the Greens in Redcar last month, launched his election campaign for the constituency at the weekend. 

And the Star can reveal the Greens will have a presence at TUC congress for the first time ever in September, when workers from across Britain meet in the party’s Brighton power base.
