Extensive protests have demanded the resignation of Joseph Muscat since the investigation into the murder of journalist Daphne Caruana Galizia has been stepped up, with information that in various ways interfered with government officials and government ministers.

The government's former chief of staff resigned earlier this week and was shortly arrested by police. He was released on Thursday.

The influential businessman Yorgen Fenech, who was arrested last week when he was leaving the country, is now described as the main suspect.

Two ministers have resigned

Over the past week, it has been reported how he has financial links with the former chief of staff and the two ministers who have also resigned.

According to Times of Malta sources, Yorgen Fenech will be formally charged with the murder in a court, after which Joseph Muscat will announce his departure in a televised speech.
