Here's why these anti-Ukip posters have been popping up in London

These anti-Ukip posters have been spotted in Soho and Farringdon.

They were put up by Crowdwish, an app which allows users to anonymously submit wishes, which are then voted on by its community and the winners enacted.

As the company's CEO Bill Griffin explained to i100.co.uk: "The idea is you take something ephemeral like a hope or wish or aspiration and turn it into something concrete."

His favourite wish so far is when the company tricked Katie Hopkins - yes that Katie Hopkins - into signing a gagging order by posing as autograph hunters at an event she was appearing at.

On Tuesday, the wish they made come true was 'I wish Nigel Farage would just give it up' - so Crowdwish made the posters and put them up in central London and online.

Griffin says they have now been inundated with "well over 100" emails from people wanting their own copies of the posters.

Expect to see one in a town near you soon - except if you live in Kent.
