Double European 100m hurdles champion Nevin Yanit has been handed a two-year suspension for drugs violations by the Turkish Athletics Federation.

Yanit won the gold medal in the 60-metre hurdles at the European Championships, in which Ireland's Derval O'Rourke finished fourth.

O'Rourke is now set to be promoted to the bronze medal position for that race as Yanit will be stripped of her gold medal.

The decision comes just three weeks after the federation banned 31 athletes for doping offences and less than a fortnight ahead of a 7 September International Olympic Committee vote on whether Istanbul, Madrid or Tokyo will host the 2020 Olympics.

In May, the International Association of Athletics Federations (IAAF) said Yanit faced a ban following "multiple positive findings in both in-competition and out-of-competition tests".

The Turkish federation said it made its decision to ban the 27-year-old athlete at a disciplinary board meeting on Tuesday.

Asli Cakir Alptekein, last year's women's 1,500 metres Olympic champion, who had already served a two-year doping ban, was provisionally suspended in May after abnormalities were detected in her 'biological passport'.
