The EU Referendum, arguably the UK’s biggest political event of the year, is approaching and the knives are out.

As Prime Minister David Cameron presents the terms of Britain’s new deal with the EU, Mayor of London Boris Johnson’s announcement that he will back the campaign to leave could be a huge blow to those in favor of staying.

It’s certainly made a wave on social.

A bigger splash

It’s fair to say that the London Mayor stole the Prime Minister’s thunder as he returned to the UK.

On Sunday alone Boris Johnson gained nearly 22k mentions across social surrounding the referendum when he announced his decision. It was 4k more mentions than Prime Minister David Cameron gained after he appeared on Sunday morning’s Andrew Marr Show looking a little worn out after a long week of negotiation.

Of course, the #Brexit debate couldn’t take place without some humorous takes.

While the exhaustive talks around Britain’s future in the EU continued, the six acts that could represent the UK in the Eurovision Song Contest were released, perhaps leading to some confusion.

I think the U.K. should leave the Eurovision too. It pays a lot and has no chances to win anyway. #Brexit @bbceurovision — Supermario (@EuroStability) February 21, 2016
