Turkish mobile operator Turkcell is claiming damages of at least $4.2 billion against rival MTN Group, which it alleges used corruption and bribery to win a mobile licence in Iran. In documents filed in a South African court, Turkcell said MTN and its former chief executive and current chairman and another former executive used wrongful and intentional interference to take the licence from Turkcell. As a result, Turkcell suffered the loss of business opportunities, turnover and profits from the licence in the amount of $4.2 billion plus interest, according to the documents seen by Reuters.
