Please could someone confirm that this is a juvenile Lesser Black-backed? It was quite a lot smaller than the herring gulls it was with (you can see that the herring gull in the background is noticeably larger). I assumed the darker plumage and more delicate bill pointed to LBB?

Thanks in advance.

Looks good for a 1cy LBBG.

Don't those notched tertials suggest a Herring Gull?

i wondered about that too, andrew. found none 1cy graellsii among these http://www.digimages.info/goebru/goebru_A1.htm with such a pattern (although i'm sure it is within a rare variation! hardly any sp. without exceptions..).

I see nothing to exclude 1cy Herring. I'm still not saying it is HG, i have no experience of graelsii.

i think pale tips to p6-p7 should be only in herring gull.

Looks like a Herring.
The edge pattern on the tertials suggest Herring over LBBG, although some LBBG can show similar pattern. However, the pale edges reach the greater coverts, which usually is not the case in LBBG, but see:

Short wing is better for Herring (provided primaries are fully grown)
