Adverts calling for an end to Brexit are popping up in parts of London.

The ads have appeared in bus stops and on trains in the London underground, but people aren’t sure who, or what group is putting them up.

On one of the adverts that appeared on a circle line train, read: “Stop Brexit: Defend Free Movement.” It had a mock underground map drawn next to it, and labelled: “Possible closure expected”.

Another advert at a bus stop has the words “Don’t throw migrants under the bus” written on it, below which is a photo of a double decker bus.

The images were taken and shared on Twitter by Another Europe, a group of “progressives fighting for an alternative to Tory Brexit”.

A spokesperson for Another Europe told Left Foot said that they had “no idea” where the ads had come from but said that it was "great to see eye catching materials making an unapologetic case for free movement.

Adding:

Abolishing free movement would amount to the biggest expansion of borders in recent history, and although the two can be separated, the surest way to save free movement is to stop Brexit.

This isn’t the first time campaigners have ‘hacked’ adverts on the London Underground.

In December last year activists put up signs which read “See It, Say It, Stop it” – a play on British Transport Police’s “See It, Say It, Sorted” - encouraging people to take action on commercial flights if they believe someone is being forcibly removed from the country.

Queer activist group Lesbians and Gays Support the Migrants placed more than 200 ads around the Piccadilly, Victoria and Central Lines.

Sam Björn from the group told The Independent at the time: “We aim to build a movement to resist this brutal, racist practice of secretive deportations and the hostile environment as a whole.”

We hope to empower everyone to take a stand and refuse to sit in silence.
