The magic of Harry Potter is to be immortalised in a new set of stamps to celebrate the popular films - with secret details that require a touch of wizardry to uncover.

The 15 stamps feature characters including Harry Potter, Hermione Granger, Ron Weasley, Ginny Weasley and Neville Longbottom.

Modes of transport from the films such as the Hogwarts Express, Hagrid's enchanted motorbike, the flying Ford Anglia and the Knight Bus are also included.

The stamps include hidden details that are only visible under ultraviolet light.

The style of the '1' depicting the value on each of the stamps will mirror the font used for the films.

Philip Parker of Royal Mail, said: 'The Harry Potter movies continue to thrill and delight audiences of all ages.

'The goal with our stamps is to capture the excitement of the Wizarding World and the heroism of the students of Hogwarts School of Witchcraft and Wizardry.'
