Meet Yanis Varoufakis, the new finance minister of Greece, who, as this photo suggests, doesn't play by the rules.
This is him arriving for talks with his UK counterpart George Osborne at Downing Street today.
To his credit, the chancellor seemed impressed by Varoufakis's more relaxed style, which he also displayed while in Paris for talks with French ministers.
Varoufakis was brought into government by the radical leftist coalition Syriza, the first anti-austerity administration in Europe since the financial crisis that has vowed to renegotiate the terms of Greece's bailout.
On his Twitter bio Varoufakis describes himself thusly: "Economics professor, quietly writing obscure academic texts for years, until thrust onto the public scene by Europe's inane handling of an inevitable crisis."
