LONDON -- Rapper Big Narstie has joined a line-up of celebs urging the British public to vote in the EU referendum this June. Along with Keira Knightley, Vivienne Westwood and Lily Cole, he's recorded a short clip with Anton Corbijn encouraging people to make their voice heard. "It takes five seconds to put an 'x' in a ballot box. Five seconds to stop others from fucking up our future," Big Narstie says in the clip, pointing out that voting is pretty quick and painless. The referendum takes place on June 23. Have something to add to this story? Share it in the comments.
