Here is a timeline of Jeremy Corbyn’s Virgin Trains journey from King’s Cross to Newcastle on August 11.
• 11.00am - Jeremy Corbyn’s train leaves London King’s Cross bound for Newcastle, where he was due to attend a Labour leadership hustings opposite Owen Smith in Gateshead.
• 11.07am - The Labour leader is captured on CCTV walking down the aisle of coach H, approximately seven minutes after leaving King’s Cross. The footage is time-stamped at 11.10am owing to the system clock being three minutes fast, Virgin Trains said. He passes “several empty, unreserved seats”, according to the rail operator.
• 11.08am - Passing through coach F, Mr Corbyn walks by several reserved seats which are reportedly empty, meaning passengers are free to sit in them.
