Iran has agreed to donate $25 million (£16 million) to Turkey’s ruling Justice and Development Party (AKP) in a move that will increase fears that Prime Minister Tayyip Erdogan is preparing to abandon the country’s secular constitution.
Western diplomats say they are alarmed by reports that Mr Erdogan has negotiated a deal with Iranian President Mahmoud Ahmadinejad for Tehran to make a substantial contribution to the campaign funds of Turkey‘s leading Islamic party.
