The London entrepreneur who erected a 35-metre sign on top of his headquarters facing the busy Waterloo Station wants other business owners to join him in voicing their concerns with Brexit.

"Everybody can play a part, and that means abandoning silence and speaking out. Posters, Billboards, the side of your building or you vehicle, are all way that you can be heard," Charline Mullins, owner of Pimlico Plumbers, wrote on a blog post on October 9.

According to Mullin's Twitter, there are "22 digital sites" across London. This video shows the sign located on Shoreditch High Street.

Mullin accused Lambeth council's requests to remove the signs as stifling freedom of speech, to which the council responded that they were not trying to censor the message, but are asking for its takedown due to the large billboard having no relation to his business.

The final Brexit deal with be announced in weeks to come, according to local media.
