1/Ten years ago, Britain voted for Brexit.
New ECFR/Mandate polling out this morning reveals something Westminster hasn't noticed: the country has quietly changed its mind — and not in the way you'd expect.
The Leave/Remain divide is dead. Here's what replaced it. 🧵

The lesson isn't "relitigate Brexit." It's the opposite: stop fighting 2016 and build a new consensus for the Britain of 2026.

This week, @markhleonard welcomes Ayşe Zarakol to explore whether today’s global crises signal disorder or a deeper shift toward “unorder,” where shared rules and assumptions are no longer relevant.

Together, they examine what this means for Europe, from letting go of old ways of thinking to redefining its role in a more unpredictable world.

Rather than restoring a fading order, the focus shifts to a more urgent scenario: what is worth preserving and how can Europe adapt to chaos to survive?

The idea of removing defence spending from the scope of fiscal rules is gaining traction. Andy Burnham mentioned it yesterday (“There’s certainly a case, when we look at the pressure on defence spending, to consider that exceptionally outside of the rules”). What might this mean?
