Malta’s Prime Minister Joseph Muscat has told associates he plans to resign over the political and legal crisis stemming from the murder of journalist Daphne Caruana Galizia, the Times of Malta reported on Friday, according to Reuters.

Muscat’s chief of staff and two members of the cabinet have already stepped aside this week over the murder case, which threatens to bring down the island nation’s close-knit elite.

Caruana Galizia, a campaigning journalist who investigated corruption, was blown up by a car bomb on Oct. 16, 2017. Her family demanded on Friday that Muscat resign, after his right hand man Keith Schembri was set free overnight.

Roberta Metsola, a Maltese member of the European parliament, said in a tweet: “If only Daphne Caruana Galizia was alive to see that even after they assassinated her, she brought the criminals down in disgrace.”

Three men have been awaiting trial for setting the bomb that killed Caruana Galizia but so far the authorities have failed to track down the person who hired them.

The case has moved quickly in recent weeks since a middleman suspected of introducing the killers to the person who ordered the hit was pardoned in return for testimony.
