Femslr American Robin
Thrush upright posture, white eye ring

It looks more like a female bluethroat than a female American robin, though rather gray of plumage and red of leg.
I'm basing this on the light patch on the malar that's underlined by a dark marking that runs into the dark marking on the chest. And the slight suggestion of a lighter line above the eye.
No other idea, really. Not my part of the world. (Bluethroats are in my Sibley's for western NA, though.)

Haven't a clue ;-)

Bluethroat is an intriguing idea -- I had figured it for some sort of lark (not my part of the world either). The hind toe and claw don't seem to be long enough for a lark, though.
One thing worth noting, in the larger view it appears to have yellow flanges at the corner of the mouth -- a characteristic common to most fledgling birds. So whatever it is, it appears to be just out of the nest.

Perhaps an immature female bluethroat. Most of the images of bluethroats show a distinct white line above the eye that is missing here.

The tail doesn't look long enough. but that may just be the angle. So I'm going to go for a pied wagtail fledgeling. If there are breeding bluethroats in the UK, I haven't heard of it.
