NAVAN Resources has appointed Mr Brian Calver as chief executive officer and managing director. He replaces Mr Paul Mihalop who did not want a full-time role in Navan, which has been expanding in Bulgaria and Spain, a spokesman said. Mr Mihalop remains on the board in a non-executive role. Navan said he would assist Mr Calver on some specific developments.

The company will now be run by a team of four executives. Mr Colin Andrew, who has responsibility for Navan's operations in Bulgaria will take charge of Hungary in June; Mr Chris Neal is responsible for Navan's operation in Spain and Portugal; and Mr David Mongey remains finance director.
