Facebook has decided to kill a 15-second ad from the U.K. Conservative Party due to intellectual property concerns. The video shows BBC journalists saying phrases such as "pointless delay to Brexit" in addition to clips of demonstrations and debates in British Parliament. 

The BBC has criticized the ad and has said that it could damage "perceptions of our impartiality." The BBC reporters in the ad are actually quoting Conservative Party leaders, such as Prime Minister Boris Johnson, and not making statements of their own.  

The Conservative Party refused to take the ad down. 

The BBC has asked Facebook to take down the video. Facebook decided the ban would be appropriate because the Conservative Party had used the footage without permission from the BBC. 

Facebook's rules on advertising say that "ads must not contain content that infringes upon or violates the rights of any third party, including copyright, trademark, privacy, publicity or other personal or proprietary rights."

The ad has been seen around 430,000 times.

Facebook has been under fire for its ad policy, as it doesn't require advertisements to be monitored by third-party fact-checkers. Last month, Twitter banned political advertising on the social media platform. 

Political advertising is going to be rampant on Facebook as the U.K. faces a general election on Dec. 12. The election could drastically change how the U.K. will leave the European Union, with Labor Leader Jeremy Corbyn promising a second referendum on the Brexit issue.

Johnson is committed to the U.K.'s exit from the bloc.

President Trump's re-election campaign has reportedly spent as much as $1 million on Facebook ads in the midst of the House impeachment inquiry into his Ukraine dealings.
