Repeat: Corbyn was proved not to have lied about not being able to find a seat on a train
Not necessarily;
At the time, Jeremy Corbyn said he was looking for "two seats together" to sit next to his wife - presumably they could have sat separately? He also had 'his team' with him and he turned down an upgrade to first class. Several passengers sitting on the floor may belong to JC's team.
The Independent have a timeline with the new footage:
www.independent.co.uk/news/uk/home-news/jeremy-corbyn-virgin-trains-row-traingate-timeline-what-happened-labour-leadership-election-a7206936.html
11 August, 11:00am: Train leaves King’s Cross in London.
11:10am: CCTV captures Jeremy Corbyn walking past unreserved empty seats in carriage H.
11:11am: One minute later, footage shows Mr Corybn walking past empty but reserved seats in carriage F.
11:30am: Mr Corbyn takes a seat on the floor to record footage for a documentary.
11:46am: Mr Corbyn is then captured on CCTV returning to carriage H and taking a seat.
12:50am: The train arrives at York, its first stop.
Virgin Trains point out that reserved seats can be used by passengers if they are not taken - there is a sign above the seat indicating at which stop the seat is required. (This is correct - I have travelled on Virgin trains myself). Jeremy Corbyn and his team were seated before they arrived at the first stop.
It gets more complicated regarding the original footage and the 'new' footage provided by Double Down News in Owlsintowels' link.
New Statesman
"one thing the video doesn't reveal, and which isn't publicised on Double Down's YouTube channel or its Facebook page, is who is behind Double Down.Companies House documents reveal that one of Double Down's directors is Yannis Mendez, the video maker who was being paid by Corbyn's team to film footage on the train, and who pitched the Guardian the article. Mendez insisted that his friend, Anthony Casey, be given a joint byline under a pseudonym. (He was billed as "Charles B Anthony".) This is what the Guardian's readers' editor found most objectionable about the story: a paid partisan activist operating as a journalist, without his affiliation being made clear to readers."
