Campaigners have erected a sculpture of a giant can of tuna outside the offices of John West in Liverpool, accusing the company of using "destructive" fishing methods to catch tuna.

Activists from Greenpeace set up the sculpture this morning, with a screen showing films including one featuring celebrity chef and campaigner Hugh Fearnley-Whittingstall.

The tuna tin is surrounded by giant damaged wildlife including a sea turtle caught up in fishing nets.

Greenpeace claims John West has broken a sustainability promise to consumers by continuing to use "fish aggregation devices" to catch 98% of its tuna, which kill other marine wildlife including sharks and endangered turtles.It has also accused the company of claiming customers can trace tuna back to the vessel that caught it when there is no way of tracing if it came from Thailand, where the fishing industry faces international concerns over environmental destruction and human rights abuses.
