Herring Gull (Larus argentatus) with extra small white apical spots

This argentatus has unusual small white apical spots on the exposed primaries and together with the advanced moult towards summer plumage this gives associations towards cachinnans or michahellis, but both these southern species can safely be ruled out on upperpart colour, proportions, argentatus-jizz and other plumage details not visible in the photos, but seen when bird in flight
