Greece's permanent representative at the UN, ambassador Anastassis Mitsialis, on Thursday signed the Optional Protocol to the Convention against Torture (OPCAT) and other forms of harsh, inhuman or degrading treatment or punishment.

The Optional Protocol had been adopted on December 18, 2002, during the 57th session of the UN's General Assembly and was implemented on June 22, 2006.

In order for the Protocol to be implemented in Greece, the process of its ratification by the Greek Parliament must be concluded.
