Last week Jeremy Corbyn was pictured sitting on the floor of a packed train to Newcastle.
He was filmed saying: "This is a problem that many passengers face every day, commuters and long-distance travellers. Today this train is completely ram-packed. The staff 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.”
He added: “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.”
But today, Virgin Trains responded that Corbyn had in fact had a seat on that train. The company said it had “to take issue with the idea that Mr Corbyn wasn’t able to be seated on the service, as this clearly wasn’t the case”, and released CCTV that it said proved there were plenty of available seats.
Whereupon a lot of people took the piss.
HOWEVER. Things then took a twist.
This gave rise to one possible scenario, which was that the CCTV showed Corbyn sitting in the always unreserved Coach H, but that he then gave up his seat and sat on the floor.
We'll come back to that, but let's just watch some more people take the piss first.
Back to the thorny issue of exactly what happened on that train. Corbyn's team issued a denial of Virgin Trains' statement.
And a friend of the man who shot the original video said Corbyn had been stitched up.
There were also plenty of people asking questions about how real all the footage was.
By now journalists were still struggling to get a grip on claim and counterclaim.
Was this a Blairite conspiracy?
Would Labour conference delegates still get their Virgin Trains discount?
Update: Virgin Trains has got in touch to confirm they will.
Questions were also being asked about the ethics of releasing CCTV that shows passengers.
Owen Smith also tried to make a joke. ☹️
BUT THEN we had another twist. A woman who took a selfie with him claimed Jeremy Corbyn DID get a seat.
Another theory was mooted on social media that involved Jeremy Corbyn being filmed walking through a first-class carriage only, but it was debunked after internet research revealed the image being circulated was of a Pendolino carriage and not, crucially, one on an East Coast Mainline train.
A sentence no one thought they'd be writing today.
By now it felt like there was only one man whose opinions on trains we'd yet to hear.
That said, there were many other bones of contention.
Anyway, here are some more people taking the piss.
Reporters were still hard at work trying to find out the TRUTH...
...when this happened.
That's right, after several hours of Twitter carnage it has finally been revealed that Jeremy Corbyn couldn't get a seat on the train to Newcastle, and then he could.
At least that's what we think happened, for now.
Update: this has happened.
