After meeting in the U.K. with British business leaders, Goldman Sachs CEO Lloyd Blankfein tweeted that many of them want to hold a "confirming" vote on Brexit – perhaps believing that popular sentiment has changed since last year's seminal decision.

Here in UK, lots of hand-wringing from CEOs over #Brexit. Better sense of the tough and risky road ahead. Reluctant to say, but many wish for a confirming vote on a decision so monumental and irreversible. So much at stake, why not make sure consensus still there? — Lloyd Blankfein (@lloydblankfein) November 16, 2017

Reality check: There is no strong political movement right now for such a vote.
