George Robinson employs his son as an office manager. Paula Bradley employs her cousin to work part-time in her office while others employing relatives include Speaker William Hay whose brother-in-law manages his office.
Although assembly rules allow it Sinn Fein has a policy of not allowing MLAs to employ their relatives as it is "unprofessional," according to MLA Pat Doherty.
