Kemi Badenoch has apologised after footage from Bloody Sunday was used in social media posts criticising a bill on legacy issues in Northern Ireland. The Conservative leader said on Saturday that she did not sign off on the use of a clip from the massacre, in which British soldiers opened fire on unarmed civil rights demonstrators in Derry, and that it was distributed by “very young people”. The video was posted on Badenoch’s social media channels on Tuesday, claiming Labour’s proposed changes would “drag” British Troubles veterans back to court.
