A museum has been forced to restrict access to a Wallace and Gromit exhibition after visitors were left queuing for hours due to a surge in popularity over the Christmas holidays.

Queues of hundreds have been forming outside the Harris Museum in Preston, Lancashire, for a chance to see original sets and models from the animated stop-motion franchise by Aardman Animations.

The recent boom in visitor numbers led the museum to stop anyone joining the lines from 13:00 GMT each day until the exhibition shuts on Sunday.

Morgan Clossick, who works at the museum, said the unprecedented demand had “just carried on each day, it’s brilliant”.
