Update: I sent details of the upper bird to Peter Adriaens a Dutch birder who is the author of the most recent article on the separation of White Wagtail from Pied Wagtail. He commented as follows;
I agree that it shows a grey rump, which would be very unusual for a yarrellii.
Its upperparts look rather dull grey with some dark streaks though, which is more typical of yarrellii but can also be shown by worn alba in summer.
The flanks look rather dark and extensively grey.
It could be a dark alba, but I am not fully convinced, and I certainly cannot exclude a hybrid.
Based on his comments it's perhaps safest to leave the bird as a possible hybrid.

As well as the wagtails there were also several family parties of Stonechat and Redstart which provided some great photo opportunities.
