Would that be a Yellow-legged Gull (Larus michahellis) George?
I'm going by the leg colour and red ring around the eye. Rather uncommon this side of the Channel.
A picture from the side. It looks like it. https://www.rspb.org.uk/birds-and-wi...lowleggedgull/. Funny dots on his tail.

Nasty neighbour taken food from your table. You have the prove, have him arrested. Humorous and great series, thanks for sharing.
