If Labour won the general election and negotiated and agreed a new deal, also an if of course, then I would support a second referendum, but only if it included all four choices by single transferable vote. My personal choice might be 1) Remain, 2) Johnson's deal or May's, 3) No Deal, 4) The Labour deal, which I assume would contain freedom of movement. Now my purpose here isn't to justify my choice and answer questions on it, it's too hypothetical to waste my time on that, my purpose is to say that I and others should have the full choice of alternatives. I would not support a rigged second referendum with only two choices.
