The sun came out for the final installment of the Harry Potter series as the film’s stars arrived for its world premiere last night.

And causing the most excitement on the red carpet was former Headington School pupil Emma Watson - better known as the movie’s Hermione Granger.

Actress Miss Watson, striking in an elaborate white dress, was greeted with cheers and screams from fans as she embarked on a marathon autograph signing session along the length of the red carpet.

Thousands of fans arrived in London’s Leicester Square for the first screening of Harry Potter And The Deathly Hallows Part Two.

Miss Watson had earlier tweeted: “I am so excited... and it has stopped raining. See you on the red carpet.”
