Mr Mann later told Sky News the EU was "fundamentally
anti-democratic" and the free movement of people under EU rules means
"we can't plan anything".
He said: "If you're a Labour voter, a former Labour voter, a
would-be Labour voter, it's perfectly acceptable for you to be voting
out, and you'll probably be in the majority of Labour voters, possibly
the large majority, in doing so.
"It's because people think that democracy needs to be shifted back to Britain."
