A delegation of 160 people has gone to Switzerland to show support for the head of Turkey's Workers' Party, Dogu Perincek, who is on trial there for publicly denying Armenian Genocide.

The general leader of the Turkish Workers' Party, Perincek is on trial in Switzerland for negating Armenian Genocide during a 2005 demonstration in Lausanne, Hurriyet reported.

Having been convicted by a Swiss court of law for denial of Genocide, Perincek filed a return lawsuit against Switzerland with the European Court of Human Rights (ECHR).

ECHR addressed Turkey, requesting a case-related letter, which was sent today by Ankara.

The response of ECHR remains to be seen.
