The International Automobile Federation (FIA) said in a statement on Thursday that the Turkish national sporting authority TOSFED and organisers MSO had been asked to attend a specially-convened meeting of the FIA's world motor sport council on September 19.

There they will "hear charges that they have acted in breach of the FIA statutes, the international sporting code and the 2006 Formula One sporting regulations."

The FIA launched a full investigation on Monday after the prize-giving at Sunday's race in Istanbul kicked up a political storm.

The trophy presentation to Ferrari's Brazilian race winner Felipe Massa was by Turkish Cypriot leader Mehmet Ali Talat, who was introduced to millions of viewers around the world as the 'President of the Turkish Republic of Northern Cyprus' in a television caption.

Cyprus has been split since 1974, when Turkish troops invaded the northern part of the Mediterranean island after a brief Greek-inspired coup. Only Turkey recognises the north.

FIA sources have said the matter is so serious that it could potentially jeopardise next year's race as well as Turkey's status within the governing body.

Turkey is due to host a round of the world touring car championship on September 24 as well as the world rally championship in October.

The FIA, which brings together 213 national motoring organisations from 125 countries on five continents, said in a statement on Tuesday that political neutrality was fundamental to its role as a governing body.

"No compromise or violation of this neutrality is acceptable," it added.
