By petition for writ of certiorari we are asked to review an interlocutory order denying the plaintiff’s motion for leave to amend the complaint by adding as a party defendant the liability insurance carrier of the present defendant. On the authority of Ross v. Bowling, Fla.App.1970, 233 So.2d 415 we grant the petition for certiorari and quash the order under review, remanding with directions to allow the amendment.
