Cardiff Bay Gulls

Any thoughts on these? Top photo is a closer shot of the standing bird in the middle shot (taken 25 minutes earlier so unfortunately the light is completely different) and bottom is a closer view of the sitting bird with its eye open. Unfortunately the sitting bird didn't move in the time I was watching it.

Pete, the sitting gull is a Yellow-legged and the gull standing looks like a Lesser-black-backed, albeit a pale mantled one.

That was my initial thinking as well but having looked at loads of photos on various gull sites thought the primary projection was a bit on the short side for YLG and wondered about argentatus HG, although I think the break in the mirror visible on the underside of the left primary 10 probably isn't right. Are there any particular features of the standing bird that rule out YLG?
