ISTANBUL, TURKEY - JANUARY 26: Ismail Cem's Brazilian daughter-in-law Andrea Sioufi Cem (L) and Ipek Cem daughter of the former Turkish foreign minister Ismail Cem attend his funeral ceremony at the Tesvikiye mosque at the Tesvikiye mosque on January 26, 2007 in Istanbul, Turkey. Ismail Cem, a former Turkish foreign minister, died on Wednesday of lung cancer at the age of 67. He served as foreign minister for three successive governments between 1997 and 2003, becoming one of the longest-serving Turkish foreign minister in recent times. His greatest achievement was forging close ties with Greece, largely due to his friendship with Greece's former Foreign Minister George Papandreou.
