The petition to deprive the head of the Prosperous Armenia party Gagik Tsarukyan of parliamentary immunity is completely illegal, and this is a fact, said Prosperous Armenia party MP Iveta Tonoyan.

“Direct prosecution is carried out against him," the deputy noted.

Armenian National Security Service investigators on Sunday searched parliamentary opposition Prosperous Armenia Party (PAP) leader, MP, and business tycoon's mansion and the enterprises belonging to him.

The NSS issued later statements on three criminal cases involving the party's leader.
