Protesters gathered once again in Valletta, calling for the resignation of Prime Minister Joseph Muscat in the wake of developments related to the assassination of Daphne Caruana Galizia.

Civil society has taken to the streets several times over the past two weeks, and the arraignment of Yorgen Fenech who was charged with complicity in the murder on Saturday has not dampened their cries for the PM to step down.

A huge crowd of protesters gathered in front of Parliament and walked down Republic Street behind a banner with the word "Justice".

Members of the Caruana Galizia family, including her parents, were among those at the front.

A stage was set up facing City Gate right in front of the law courts building, where the Great Siege Monument is situated and is serving as a makeshift memorial to the slain journalist.

Copies of the photo which shows former chief of staff Keith Schembri with the alleged middleman Melvin Theuma, taken in Castille, were affixed to the gate leading to the law courts.

Muscat has steadfastly refused to take political responsibility, even after his chief of staff was forced to resign as he was arrested in connection with the case.

Keith Schembri was named in the investigation, but the police released him on Thursday after two days of questioning.

Once again protesters are carrying placards calling for justice and for the resignation of the PM. Many of the protesters are carrying Maltese flags, and also photos of Daphne Caruana Galizia.

There are indications that Muscat could step down in January, but there has been no official statement.

At the end of the official activity, organised by Occupy Justice and Repubblika, some protesters blocked the road near the War Memorial in Floriana, shouting "justice".
