Malta government chief of staff Keith Schembri resigned on Tuesday, Prime Minister Joseph Muscat told reporters, as police continued their investigation into the 2017 murder of journalist Daphne Caruana Galizia. Police sources said Schembri was assisting them in the case. Schembri had been facing pressure to resign because of his alleged financial ties to businessman Yorgen Fenech, who was detained last week as a person of interest in the murder probe.
