The mysterious German behind Orban's Russian deals

In August 2013, Hungarian prime minister Viktor Orban welcomed Sergey Kiriyenko, head of Russia's state-run nuclear energy company Rosatom, in Budapest.

It was not their first meeting — but it was probably their most important one. According to Hungarian government sources, it was then that Orban decided to contract Rosatom to expand Hungary's Paks nuclear power plant — a choice made without a public tender.
