Disco 2 Broken Rear Seat Release

The flap you lift has is broken on the drivers side rear seat. I can drop the rear seat by grabbing the broken bit in the middle with some pliers. However I would like to fix it permantly, is the lever available does anyone know? Or is it a whole new assembly? Part numbers would be a great help too if anyone would be so kind..
