A fuel injector comprising a nozzle body provided with a first bore and defining a first seating, a valve member engageable with the first seating to control fuel flow from the first bore towards an outlet opening located downstream of the first seating, the valve member being provided with a second bore defining a second seating. A valve needle is slidable within the second bore and is engageable with the second seating to control fuel flow from the second bore towards a second outlet opening provided in the valve member.
