Even the Last Night of the Proms can't avoid the country's Brexit crisis, as different sides of the debate clashed at the event last night.
While Remainers waved EU flags to show their support for staying in the union, Leavers had their own pro-Brexit banner.
The two sides were involved in a scuffle during the middle of Jerusalem, with Remainers reportedly trying to pull down the 'Brexit Now' banner.
The incident was caught on camera, which also captured a man wearing a t-shirt for the far right For Britain party.
Anti-Brexit campaign group the EU Flags Proms Team said it had collected 50,000 EU flags to hand out across the various Proms events.
Spokeswoman Kate Hobbs said she hoped the flags would be a "timely reminder" to the audience that music is a "universal language which unites people".
"We were keen to demonstrate that it is possible to be patriotic at the same time as maintaining a European and internationalist identity," the EU Flags Proms Team added.
But perhaps inevitably the use of political flags during the event, albeit for the fourth year in a row, has divided opinion.
One Twitter user wrote: "The Proms is ruined now, because it isn't about the one thing it was for, the music! The people have made it into a political statement.
"It's made more news than the actual performance! How sad for the musicians that put hours of practice to be topped by flag wavers."
"This country is so split," another added. "I'm of the opinion the majority would sell out their own UK status in preference to become 'solely European'."
The Proms is an eight week celebration of classic music held every year at the world famous venue, with the Last Night a patriotic celebration of popular classics.
Union Jack waving is part of the tradition but EU flags have appeared in large numbers since the 2016 referendum.
The BBC said it tried to avoid giving "undue prominence" to the flags and its "primary focus is on the musicians and their performances".
Speaking about the pro Brexit banner after the event outside the hall, one Leaver said: "We just wanted to make our point on behalf of 17.4million people, we queued up early and got in."
