The European Parliament has called on Malta's prime minister, Joseph Muscat, to quit immediately over his handling of the investigation into the murder of the journalist Daphne Caruana Galizia, as it declared there were "serious and persistent threats" to democracy and the rule of law.

Greece's Supreme Court will on June 14 rule on whether to execute European arrest warrants issued against a Russian whistleblower who helped a Maltese journalist investigate money-laundering and corruption.

Malta wants to arrest former bank employee Maria Efimova for allegedly providing false evidence, making false accusations to authorities, and appropriation of funds.

The Russian whistleblower Maria Efimova, who is being detained in a prison in Thebes after her arrest on March 20 by Greek authorities executing two European arrest warrants, explains in an interview with Kathimerini how she fed information to the murdered Maltese investigative journalist Daphne Caruana Galizia, helping her reveal the alleged corruption at Pilatus Bank.

A former bank employee who ignited a political scandal in Malta when she became a source for an investigative journalist who was murdered last year has surrendered to Greek police and been arrested at Malta's request, a senior Greek police official said on Tuesday.

Maria Efimova, a Russian whistleblower who fed information about secret bank accounts in Malta to murdered Maltese blogger Daphne Caruana Galizia, surrendered to Greek authorities on Monday night.

Saying that she was in fear of her life, the former Pilatus Bank employee reportedly turned herself in to police at Athens's central Syntgama Square metro station.
