Virgin, which in August had to swallow the government's decision to remove its franchise for the west coast mainline, which Osborne had just used, confirmed that he had travelled in first class on a standard class ticket, initially at least.
"The chancellor, who was travelling in first class accommodation, held a standard class ticket," a spokesman for Virgin said. "As soon as the train left Wilmslow, an aide went to find the train manager to explain the situation and arrange to pay for an upgrade. It was agreed that the chancellor would remain in first class and an amount of £189.50 was paid by the aide to cover the upgrade for Mr Osborne and his PA. The situation was dealt with amicably between the train manager and George Osborne's aide. At no time was there a disagreement or a refusal to pay for the upgrade. Nor was there any discussion between the train manager and Mr Osborne."
It chimed with the Treasury's account. "The chancellor got a different train than planned due to diary change following a series of meetings in his constituency," a spokesman said. "As he had no seat reservation on the new train, which was crowded, he decided to upgrade – and obviously intended and was happy to pay. An aide sought out the train manager and paid the ticket upgrade."
