The Who frontman said Brussels had become so bloated its influence was now "detrimental" and the organisation was doomed to fail.
In an interview with Sunday Times magazine yesterday, he also revealed he had not ruled out voting for Nigel Farage's UK Independence Party.
He said: "I've met Nigel but I don't know who I'll vote for. I'm agnostic at the moment.
"I can't stand the bureaucracy of the European Union. It's detrimental to the whole place.
"They've made some decisions now where I think it can only fly apart at the seams. Sooner or later. Hopefully sooner."
