Maltese businessman Yorgen Fenech has been charged with complicity in the murder of investigative journalist Daphne Caruana Galizia in 2017, reports BBC.He pleaded not guilty to that charge and four others others including membership of a criminal gang.
Relatives of the assassinated blogger were present in the court in Valletta.
The investigation into Caruana Galizia's death has rocked the island's government. Prime Minister Joseph Muscat is under pressure to resign.
His chief aide, Keith Schembri, quit this week amid reports he was being questioned by police, while Tourism Minister Konrad Mizzi also resigned and Economy Minister Chris Cardona took the decision to suspend himself.
Three people are awaiting trial for Caruana Galizia's murder in a car bombing but the police investigation is now focusing on who ordered the killing and why.
Who is Yorgen Fenech?He has been repeatedly questioned over the killing since trying to leave the island on his yacht on 20 November, and sought a pardon in return for providing information but his request was rejected.
Maltese media allege he was familiar with Melvin Theuma, a taxi driver with links to criminal enterprises who has been described in local media as a potential "middleman" in the murder.
