The British Olympic Association is threatening legal action against Brexit campaigners Leave.EU over the unauthorized use of pictures of their athletes, Sky News reported Wednesday.

The BOA gave the grassroots Brexit movement until 5 p.m. London time Wednesday to remove the images, and other intellectual property, contained in a video posted on social media Monday.

According to the BOA, this intellectual property included the words Rio 2016, Team GB, Olympics, Olympian and Team GB logos, as well as the images of Team GB athletes.

Leave.EU posted the video, which displays several British Olympic medal winners including tennis player Andy Murray, distance runner Mo Farah and gymnast Max Whitlock, to try and make the point that Britain did not need to be in the European Union in order to be great.

The issue caused some consternation on Twitter, with Scottish silver medal-winning cyclist Callum Skinner tweeting back: "thanks [for] the support … but I wish you wouldn't use my image to promote your campaign," followed by the EU and U.K. flags.

Leave.EU issued a defiant statement addressed to "Remainiacs" saying: "We understand they're still p****d that the majority of people do believe in Britain and want us to succeed as an independent country outside of the crumbling EU, but to try and stop us promoting just how great we're doing reeks of desperation."

Sky News reported the group vowed to "continue to publish stories that showcase how Britain is thriving as we leave the European Union."
