Apologies for the quality of the photo, this is from my phone. I wondered which of the Gulls this is, as I haven't quite come to grips with them yet... thanks.
I say black-headed as well. It's the eye-ring that clinches it - little gulls lack these, making the eye very difficult to see.
Dark wing tips, long legs, size & bill shape, Black-headed Gull in my opinion. I've been wrong before though.!! :-)
Thanks both, appreciate your help.
Looks like a black-headed gull in its summer plumage, winter plumage is a little black spot near the ear!
