(Adds government statement)
The Nationalist Party has called on the Prime Minister to call a meeting of the Citizenship Monitoring Committee.
In a statement, the PN said that the committee, set up last year, had never met and was not functioning.
Party leader Simon Busuttil said Prime Minister Joseph Muscat should give a detailed account of all citizenship applications submitted so far for the sake of transparency.
In a reply, the government said a committee meeting will be called in due time.
