Citizenship should never be for sale, ADPD - The Green Party, said in a statement.

It was reacting to the judgement by the European Court of Justice that ruled that Malta's golden passport scheme is in breach of EU law.

ADPD said it has been pointing out the inherent flaws in this scheme since its inception in 2014.

"Citizenship should never be for sale. A hefty price tag does not establish a genuine link to the country. In addition, Maltese citizenship grants backdoor entry to the Schengen area. We need to utilise the benefits and privileges granted to us responsibly. Our actions bear direct consequences on our allies in Europe," it said.

Party Chairperson Sandra Gauci said: "The Green Party expects immediate compliance with EU laws and the prompt cessation of the Golden Passport scheme; citizenship obtained through this scheme which has been declared illegal by the European Court should be revoked forthwith."
