BBC Sport's live coverage of Sunday's FA Cup Fourth Round clash between Wrexham and Sheffield United accidentally showed a fan holding a poster stating: "F*** the Tories".
The message was displayed under a flap of a fan in the home end holding a placard in the shape of the FA Cup trophy. Three months previously, Wrexham did not allow their striker Paul Mullin to wear his custom-made "f*** the Tories" boots.
The 27-year-old revealed the anti-Conservative party boots on social media with pictures taken at Wrexham's Racecourse Ground; the club are owned by Hollywood stars Ryan Reynolds and Rob McElhenney. The duo said at the time that the photos were taken without their knowledge or permission.
