Sir Patrick Stewart has criticised the "disarray" in the Labour Party, as it has descended into bitter infighting over who should be its next leader.
In an interview with HuffPost Live The Star Trek actor attacked David Cameron's "codswallop" but appeared dismayed at the current state of Labour.
Asked whether it was right that people had to "tighten" their belts to help the economy recover, he said: "Some of us have to tighten our belts, some of us don’t need to. And so this whole talk... I am glad to see our prime minister has shut it up now, the whole thing of One Nation was such codswallop. The Conservative Party has never believed in One Nation.
Sir Patrick, who is a longtime supporter of Labour, added: "The Labour Party are in complete disarray.
"How to return to a world where we can say, first and foremost, we believe in fairness because that has been absent from British politics for quite a long time."
In June, Sir Patrick told BBC Newsnight that Ed Miliband should not have resigned straight away after the election. "I'll tell you exactly what I think should've happened. I think Ed should still be there," he said.
"I think if he did some terrific things and he made some mistakes but I think the biggest mistake he made was resigning and walking out on the party."
Speaking to HuffPost Live, Sir Patrick also said politicians should learn from his Star Trek character, Captain Picard.
"I wish that politicians would spend more time watching Star Trek: The Next Generation. Because unlike my predecessor, Captain James T. Kirk, Jean Luc Picard believed first and foremost in negotiation. He was a diplomat before he was a warrior. Talk, talk, talk and keep on talking. That would be a great message for the world to absorb," he said.
Sir Patrick was speaking in the United States as back in the United Kingdom, leftwinger Jeremy Corbyn appears on track to cause a major upset by beating Andy Burnham, Yvette Cooper and Liz Kendall to the Labour leadership.
