The Supreme Court in India has said Italy's envoy does not have legal immunity, in an escalating row over Rome's refusal to return two marines charged with murdering two Indian fishermen.
India's chief justice says the court had lost trust in Italy's ambassador, Daniele Mancini, and reiterated last week's order for him not to leave the country.
The two marines, Massimilian Latorre and Salvatore Girone, shot dead two fisherman off the coast of Kerala last year believing them to be pirates.
They were allowed to go home to vote in last month's Italian election on condition that they return to stand trial.
Mr Mancini had given his personal assurance they would return within four weeks as ruled by the court.
