Prince Harry has blamed the U.K. tabloids for the breakdown of his relationship with ex-girlfriend Chelsy Davy. On Tuesday, the Duke of Sussex stepped into a courtroom witness box to hold the British press accountable for its "destructive" role throughout his life.The 38-year-old is the first senior member of the British royal family to testify in over a century as he held a Bible in his right hand and, in a soft voice, swore to tell the "whole truth and nothing but the truth" in the High Court in London.
