UN human rights expert Agnès Callamard has been involved in some of the most talked-about stories of the past year, from investigating the killing of Saudi journalist Jamal Khashoggi, to condemning the arrest of Wikileaks founder Julian Assange.

Ms. Callamard has also been highly critical of Malta’s response to the killing of investigative journalist Daphne Caruana Galizia, and in October, alongside fellow Special Rapporteur David Kaye, she called on the Maltese authorities to do more to find those responsible for her death.

Shortly after that appeal, she sat down with Conor Lennon in the UN News studios in New York.

He asked her if she was surprised that the investigation into the death of Ms. Galizia has not made more progress.
