The Brussels summit, which brought together the leaders of all EU member states, did not particularly focus on the UK's Brexit. The official agenda was dominated by migration, trade and Russia. However, Brexit still loomed large, particularly at a working dinner last night, where Mrs May gave a brief ‘Brexit update’. Open discussion has been ruled out but Brexit will remain the red, white and blue elephant in the room during all the official discussions tabled at this summit. There is a distinct hardening of attitudes, even amongst Britain's closest EU allies like Germany. Leading Brexiteers boast confidently that Europe's most powerful nation is bound to push hard for a good EU deal for the UK. They cite German self-interest and a four-letter word - cars. The UK is Germany's third largest export market, while one in five German cars is sold in Britain. See:
