How to solve a problem like Brexit?
Ostensibly, it’s the reason for Tony Blair’s return to fray. He wants a second referendum to reverse the public’s decision to quit the EU back in June, but polls show the voters simply don’t regret the decision.
To get them to change their minds, the facts must change.
Ever the pragmatist, Blair knows full well this means abandoning free movement of people as an article of faith for the pro-globalisationists of British politics, of which, he remains the undisputed leader.
Could he follow contemporary Labour luminaries like Yvette Cooper, Andy Burnham, Rachel Reeves, Chuka Umunna and Hilary Benn who have each recently called for an end to free movement?
The impact of mass migration was the defining issue of the campaign and reforming it is an essential down payment in securing any fresh plebiscite. But, even then, there’s no guarantee one can be justified.
Of course, it also requires Europe to even discuss a special deal for Britain, which, variously, Angela Merkel, the Commission and east European Member States have all flatly rejected.
But we are through the looking glass in 2017.
And if John Major could secure his Maastricht Treaty opt-outs from joining the single currency and social chapter, Blair might calculate that a fresh deal on free movement is achievable.
After all, 2017 may be another tumultuous year for the EU, if Marine Le Pen wins the French presidency, or if Merkel is ousted in German federal elections later in the year.
Buying off the truculent Brits with a concession on free movement might seem the cheap option for a bit of stability.
