In reply to Jim Lancs:
While a WTE seems more likely, due to their distribution being much wider than golden eagles and they, in my experience, turn up closer to human than golden eagles, it would be quite difficult to mistake a WTE.
Confusing a buzzard with a golden eagle is not that surprising; from a distance, sometime at a difficult angle and with a brief view, they do no immediately look that different. A WTE is something else.
While there are some superficial similarities between buzzard and golden eagle, a WTE has a different shape and is HUGE.
Quite a useful guide to buzzards and eagles - https://www.bto.org/develop-your-skills/bird-identification/videos/identify... - but so often we don't get a good look at them.
