Did Greta do a Corbyn?

Has Greta Thunberg been caught out repeating the same trick as Jeremy Corbyn? Thunberg tweeted an image of herself sitting on the floor of what she described as an 'overcrowded' train on her way back to Sweden:

Traveling on overcrowded trains through Germany. And I’m finally on my way home! pic.twitter.com/ssfLCPsR8o

However, the tweet quickly sparked controversy with German train operator Deutsche Bahn appearing to derail Greta's suggestion that she had been forced to sit on the floor, claiming she had a 'seat in first class':

Greta quickly hit back, claiming that 'overcrowded trains' are a 'great sign':

Our train from Basel was taken out of traffic. So we sat on the floor on 2 different trains. After Göttingen I got a seat.This is no problem of course and I never said it was. Overcrowded trains is a great sign because it means the demand for train travel is high!

Back in 2016, Jeremy Corbyn found himself in a similar situation after he published a video of him sitting on the floor of a supposedly overcrowded train, only for Virgin Trains to share CCTV footage showing that the carriages were less than heaving. Perhaps not the last time a left-wing icon has been found to be full of hot air...
