Kate Middleton and Prince William have testified against Prince Harry in court. The article is based on a satirical video that was posted on YouTube.
The video, which is titled "BREAKING NEWS! Kate & Wills TESTIFY AGAINST Harry! EXPLOSIVE MOVE DRAGGED WALES TO COURT," is a comedy sketch that is not meant to be taken seriously. The video features actors who are pretending to be Kate Middleton, Prince William, and Prince Harry.
The video is not real news, and it should not be taken as such. There is no evidence that Kate Middleton and Prince William have testified against Prince Harry in court. The video is simply a satirical take on the current state of the royal family.
