STOCKHOLM/ISTANBUL Aug 7 - TeliaSonera said on Friday an arbitration tribunal ordered Turkey’s unlisted Cukurova group to sell its remaining stake in Turkcell Holding to the Nordic telecoms firm.

The transfer, for $3.1bn in cash, would give TeliaSonera a majority stake in Turkcell, Turkey’s top mobile operator, in which Turkcell Holding owns 51 per cent.
