Wildlife Photographer of the Year winners

The annual Wildlife Photographer of the Year competition winners have been announced by the Natural History Museum, which has run the event for 50 years.

The winning entry was by Michael Nichols, whose snap of a pride of sleeping lions was deemed the best of an incredible bunch of entries of everything from big cats to tiny mice. Below are the winners of the key categories.
