Molly McCann managed to lead the crowd at UFC London on Saturday night in a "F*** the Tories" chant during her post-fight speech.
The 32-year-old had just scored her second KO win at the O2 Arena in four months, beating out opponent Hannah Goldy.
After knocking Goldy out in the first round, she was taken aside for an interview with Michael Bisping.
McCann proceeded to say in the Octagon: "Guys, have a listen [to the crowd]. I don’t know if I’ve ever seen this in combat sport in the UK, [fans] getting behind a female athlete [like this].
"You working class... everybody who’s come for me, I appreciate you. It’s those walkouts, it’s that energy that you bring, that’s what gets [fighters] finishes.
"To see everyone else on this card who didn’t want it as much, they let you down. I will not let you down, I’m not Everton Football Club."
Then hitting out against the UK's Conservative party, the Liverpool native said: "Can I just get you all to sing one thing? Okay, I’m not gonna swear..." she went on, before leading a chant which saw her mime the word "f***" as fans proceeded to sing in full: "F*** the Tories."
In other UFC news, Paddy Pimblett used his own post-fight interview to call on men to be courageous in talking more openly about their mental health.
The 27-year-old said: “I woke up on Friday morning at 4am to a message that one of my friends back home had killed himself. This was five hours before my weigh-in. So Ricky, lad, that’s for you.
“But there is a stigma in this world that men can’t talk. Listen, if you’re a man and you’ve got weight on your shoulders and you think the only way you can solve it is by killing yourself, please speak to someone, speak to anyone.
“People would rather... I know I’d rather have my mate cry on my shoulder than go to his funeral next week. So please, let’s get rid of this stigma, and men, start talking.”
