The Maltese Prime Minister’s chief aide, and tourism minister have both resigned after an escalation of political turmoil relating to the death of an investigative journalist in the Mediterranean country two years ago.

The journalist, Daphne Caruana Galizia had accused Keith Schembri, chief aide to the Maltese Prime Minister Joseph Muscat, and Konrad Mizzi, Muscat’s tourism minister, of corruption, shortly before she was killed in a car bombing.

Malta’s economic minister Chris Cardona has also suspended himself. All three government officials who have stepped down deny any wrongdoing.
