Bird of Prey?

Hi, I was wondering if anyone could help to identify this bird?

I was on a walk today (West of Scotland) and saw this bird flying. It wasn't flapping, just gliding along. I thought it was buzzard-like in size, however the proportion and shape of the wings threw me off as they looked more eagle-like. Unfortunately the pictures I did manage to take didn't capture the plumage details very well as it was relatively far away, so I have had to heavily crop them and edit them to make them easier to see, but they still aren't very good, so any help would be appreciated!
