Aircraft
I was pilot flying on this flight. Before departing an electrical smell was noted in the cabin by the FA (Flight Attendant) and CA (Check Airmen). Maintenance searched for the source and could not duplicate it. Enroute; the cockpit PA /CALL/ EMER lights illuminated simultaneously on the PA module. We had no communication with the cabin at that point due to the PA system malfunction. Moments later the FA knocked on the flight deck door to inform us that the smell returned. We were at 9000 ft. The CA and I decided to land at [the nearest suitable airport]. The landing was normal.
Air carrier First Officer reported an electrical fumes in the cabin prior to departure which Maintenance could not locate and dissipated on their own. Enroute the fumes returned and the flight diverted.
