There is a protest of the Tory party conference in the UK, organised by pro-remain orgs, so really being put forward by FBPE types (a lot of extremely pro-EU folks who stumble into being racist a LOT). This is meant to be a large march/protest to bring leavers around to their cause and show they can be fun.
The march has a theme: circus. They are dressing up as clowns.
"Hundreds of clowns in favour of remaining in the EU protest Tory party conference"
Kill me.
