Robert Agius and Jamie Vella were convicted last week of their role in the anti-corruption journalist’s murder in 2017

Two men have been sentenced to life in prison for supplying the car bomb that killed the anti-corruption journalist Daphne Caruana Galizia in Malta eight years ago.

The sentencing on Tuesday of Robert Agius and Jamie Vella, reported to be members of the island’s criminal underworld, marked a significant step in the long campaign to bring those charged with Caruana Galizia’s murder to justice.

Her death in October 2017 sparked outrage across Europe and embroiled Malta’s governing party in accusations of a coverup, ultimately leading to the resignation of the then prime minister, Joseph Muscat.

Prosecutors have brought charges against seven people, including a millionaire businessman who is still awaiting trial.
