The charms of variable geometry

These concessions may seem esoteric, but Charles Grant of the Centre for European Reform, a think-tank in London, thinks they are important - and not just for Britain. What the EU has conceded is, in effect, that its members are now moving not just at different speeds but towards different ultimate destinations. This is why true believers in a federal Europe hated the deal given to Mr Cameron. But some other non-euro countries, like Sweden, Poland and Hungary, liked it. Indeed, if Brexit prevails on June 23rd, they may try to secure the same deal for themselves. In the EU, it seems, variable geometry is here to stay.
