A passer-by took the perfect wedding proposal photograph of an oblivious couple, who were having the romantic moment in a secluded spot by the Durdle Door in Dorset.

There is a search for the mystery pair, as the picture was taken from a unique vantage point which captured both the natural structure and the couple in the middle of the proposal.

Tracey Hollis-Rowe, 44, was photographing idyllic Durdle Door in Dorset when a man and woman appeared in the foreground.

The man, as she snapped photographs of the scene, suddenly knelt down on one knee and produced a jewelry box containing an engagement ring.
