Another grey Monday in late January. For Hughie Wong, a partner in the London office of Walkers, it is the morning after the night before. He is not alone. The previous day the Greeks had gone to the polls and voted into government Syriza, the radical-left party whose anti-austerity agenda risks the country exiting the euro, stoking instability throughout the European Union (EU).

Uncertainty hangs in the air. “It is not yet clear what the Greek government will do,” comments Wong. He had listened carefully to Yanis Varoufakis, since confirmed as Greek finance minister, on that morning’s BBC Today programme. “He was quite frank in that interview, saying that we have a democratic mandate to push back on austerity, but he was careful not to close the door on anything.”
