In October 2017, investigative journalist Daphne Caruana Galizia died in a car bomb attack. Muscat promised to "leave no stone unturned" in the subsequent investigation. The opposition blamed Muscat for what they deemed a "political murder" and for the collapse of the rule of law in the country. In the following two years, Muscat spoke very sparingly of the Caruana Galizia case and of the periodic protests that took place in Valletta. Government employees were tasked with clearing a makeshift memorial to Caruana Galizia at the Great Siege Monument in Valletta on a regular basis.
