A Metropolitan police security officer, Chris Ham, 21, told the high court in London today that Mr Jones, the MP for Clwyd South for 20 years, swore at him after he “politely” asked to see his pass at Portcullis House in Westminster. Mr Ham, who said he had never seen Mr Jones before the incident, described the outburst as having left him “shocked and flustered”.

Giving evidence on behalf of Mail on Sunday publisher Associated Newspapers, Mr Ham said: “His immediate response was to tell me to fuck off and that he was a member of parliament. I again asked politely, persisted. His second response was ‘Fuck off, you should know who I am, you don’t have the right to question me, you are only security.'”
