Mystery bird

The following email was received from Peter Howe today:

Interesting photos having looked as close as possible and flicked through the field guide can vulture be ruled out on the tail, all vultures tails are too short apart from Egyptian and bone crusher, but wings of bird in question seem too long to be Egyptian, eagles wise surely the wing are not broad enough for white tailed, with the evident long tail and what seem to be yellow feet combined with white flashes on the underwing possibly point to golden?? Comments and location would be welcome.
