Labour backs second referendum: Is this really happening?

Advocates for a second referendum should not get over-excited just yet. There are still massive obstacles to securing it, let alone winning it. Labour support does not create a parliamentary majority. A chunk of Labour MPs - probably around 50 of them - would vote against any amendment on a People's Vote, regardless of whether the leadership backed it or not. This approach also involves backing for May's deal, albeit with a rather massive snarling caveat, which may make many opposition MPs queasy. That could worsen the numerical problem. And there are only about a dozen Tory MPs who are prepared to support such an idea right now. That means a lot of minds need changing to secure a Commons majority
