If the Govt did move first on a #FinalSay ref, the Labour leadership will be left in the impossible position of either opposing something the vast majority of their members and voters support, or supporting the Tories.
Huge numbers of people would never forgive them for either.
Either is also likely to blow any electoral gains they might hope to make in 2022 by not acting and letting the Tories own the catastrophe.
Indeed, doing either is very likely to end any idea of electoral gains, and make their only strategy damage limitation as they haemorrhage voters.
Even worse would be winning a GE and then signally failing to either renegotiate the Withdrawal Agreement (which they cannot now support due to the ill-conceived decision to attack the Backstop, despite it being a fundamental element of any WA) or the future deal they promise.
Not only would negotiations on a future relationship require a WA with the backstop now, but we know that the deal inn the future relationship they propose in fundamentally unachievable.
Not a good look in a 2024 election to have either failed to get a deal, or agreed to one that was miles from what was promised.
So there is a choice for the Labour Leadership. Move first, or face the impossible task of keeping those members and voters you either a) ignored by opposing a ref; b) feel betrayed by you supporting the tories; or c) see that you couldn't deliver what you promised.
