2nd winter Yellow-legged gull?
Note special head shape with "bulge in front of the eye" and darker, less bluish grey back than HG.
Almost all white rump and rather dark inner primaries. Single whiter feathers (3rd gen) can be seen among both rectrices and secondaries.
Head and blunt tipped bill shape can be discerned, with a little good will...
