The High Court in London has thrown out an attempt to prosecute Tory leadership contender Boris Johnson over claims made by Vote Leave during the Brexit referendum.
Lady Justice Rafferty, sitting with Mr Justice Supperstone, overturned a decision by a lower court that there was a case to answer.
Lady Justice Rafferty told Mr Johnson's barrister, Adrian Darbishire QC: "We are persuaded, Mr Darbishire, so you succeed, and the relief that we grant is the quashing of the summonses."
Marcus Ball, a Remainer, had crowdfunded more than £200,000 for a private prosecution, and presented his case at Westminster magistrates court last month and on Wednesday, 29 May, District Judge Margot Coleman ruled the private prosecution could go forward.
Mr Johnson's lawyers claimed Judge Coleman had got the law wrong.
The Uxbridge and South Ruislip MP's legal team said the offence of misconduct in public office was about the clandestine abuse of power and Mr Johnson's claim was not secret.
Many political commentators had seen the case as setting a dangerous precedent for politicians.
