When you look at the parties that have made a decision, Labour's natural home should be with the second referendum supporters.
Labour is rarely on the same side as UKIP, the DUP and the Conservatives - but the issue isn't that simple for the party.
Backing a second referendum has always been a difficult issue for Labour because unlike Change UK, the Greens and the Liberal Democrats, they have a significant number of supporters who are Leave voters.
Thirty-five per cent of Labour voters in 2015 also voted for Brexit, but polls have also shown that as many as 72 per cent of Labour members back a second referendum.
There’s no easy way to keep both of those groups happy and that's why Labour has tried to avoid making a decision for as long as possible.
But with European elections in three weeks, it's time for them to make a choice - are they for or against a People's Vote?
