Tata is to take steps to cease operations at its steel plant in Port Talbot earlier than planned because of a strike by Unite, workers have been told.

The company had been planning to shut down one of the blast furnaces by the end of June and the second one by September.

But workers at the South Wales site have been told that because of the strike by members of Unite, from July 8 Tata can no longer be assured of sufficient resources being available to ensure safe and stable operations.

A message to employees said: “Therefore, we are left with no alternative but to take preparatory steps to cease operations on both blast furnaces and safely isolate them no later than July 7.”
