Leeds City Transport 1206, UNW206H, a 1970 Park Royal bodied Daimler Fleetline CRG6LXB/36. One of 30 similar vehicles, it is carrying the early version of the WYPTE livery which would date the photo to the mid 70s.
These never seemed to be the "happiest" of vehicles, it being commonplace to see them sitting down over the back axle. 1206 was withdrawn from service in 1981.
