Jeremy Corbyn had a seat on a train journey he suggested was so “ram-packed” he had to sit on floor, according to CCTV footage seen by The Telegraph.
The Labour leader walked past rows of empty seats before sitting on the ground between carriages for a video in which he attacked the state of Britain’s railways, footage shows.
Minutes after filming the video, during when he called for renationalisation of the railways, he took up a seat for the remaining journey of his London to Newcastle trip.
The footage emerged after Mr Corbyn was praised for sticking to his principles after it was reported he rejected an offer of a first class ticket and instead sat on the floor.
Mr Corbyn was travelling to Gateshead for a debate against his readership rival Owen Smith.
In a video published on the Guardian’s website, Mr Corbyn said: “This is a problem that many passengers face every day on the trains, commuters and long-distance travellers.
“Today this train is completely ram-packed. The staff on the train are absolutely brilliant, working really hard to help everybody.
“The reality is there are not enough trains, we need more of them and they’re also incredibly expensive. Isn’t that a good case for public ownership?”
A report of the incident said Mr Corbyn was “famed for standing up for his principles”, adding that he was joined by other seatless commuters on the trip. Mr Corbyn was said to have turned down the offer of a first class ticket.
He is quoted as saying: “Is it fair that I should upgrade my ticket whilst others who might not be able to afford such a luxury should have to sit on the floor? It’s their money I would be spending after all.”
The footage was posted on the day the government announced that regulated rail fares will rise by 1.9 per cent in January – a higher than expected increase.
Mr Corbyn has made renationalisation of the railways one of his key pledges in both his previous leadership race last year and the one running this summer.
One of his 10 campaign pledges this summer includes the line: “We will bring our railways into public ownership and build democratic social control over our energy.”
Mr Corbyn also recently backed the train worker strikes that have caused delays this summer, saying he “absolutely” supported the decision by RMT union to take industrial action.
Chris Bryant, the Labour MP who served in Mr Corbyn’s shadow cabinet, said: “The biggest sin in politics is hypocrisy. I think a lot of people will feel led up the garden path by this.
“This makes Corbyn seem like a charlatan, pretending to be one thing when he is really quite another. I think voters are sick of that already.
“Apart from anything else, people who do have to sit on the floor regularly will be furious with him.”
Neil Coyle, the Labour MP for Bermondsey and Old Southwark, said: "Labour members wanted an end to spin.
"But it was spin that Jeremy didn't have a seat on the train, spin that Labour did well in May, when we got a century low vote share in Wales and came third behind the Tories in Scotland, and spin he made over a 123 speeches in the EU referendum campaign when he made 10."
A spokesman for Mr Corbyn has been contacted for a comment.
