If you only know one thing about European summits, it should be this: agreements aren’t worth the paper they’re written on. The fact something has been publicly announced, even written down in 4am post-summit communiques, means nothing.
Yet another European summit has been discussing yet another urgent issue, and yet again it is one that was supposed to have been agreed at a previous summit: banking union. The wrangling this time extends as far as the question of whether what was previously agreed is even legal.
Once again the deal was struck in the early hours of the morning, and once again Europe’s leaders hailed it a success.
