A top official from media advocacy group Reporters Without Borders is still waiting for an answer to her request to meet with the police commissioner in connection with the Daphne Caruana Galizia case. 

UK Bureau Director Rebecca Vincent said her request to meet with the police boss since last Monday has been met with a mere acknowledgement.

"In the interest of transparency it would be great if he would be willing to talk to us about what's happening," she told Times of Malta. 

She is hoping to receive more details about the investigations into the murder of Ms Caruana Galizia, who was killed in a car bomb last October. The police commissioner has been conspicuously absent, eliciting criticism from several quarters.

Three men have since been charged with the murder but the mastermind is believed to be at large.

Ms Vincent said that all those involved in the October 16 attack must be brought to justice - and any degree of impunity will leave the door open for repeat attacks.

She is also in Malta to monitor the 34 ongoing libel cases against Ms Caruana Galizia, which the assassinated journalist's family have demanded to proceed.

Asked whether she believed the media landscape in the EU had changed after a Slovak journalist was killed last Sunday, Ms Vincent replied: "This time last it would have been shocking to think of cases like this happening in Europe... It's really opened a lot of eyes."
