Deputy Labour leader and regular on the festival circuit Tom Watson picked the wrong weekend to let loose.
As Labour's top ministers revolt against party leader Jeremy Corbyn following a vote of no confidence, Watson is en-route back to London after partying until 4am at Glastonbury festival.
It was a boozy Saturday for the politician. Watson live-blogged his day at the festival on social networking app Snapchat, sharing a photo of a bottle of craft beer with the caption "it's come to this".

Watson also posted a photo of himself drinking a can of Thatchers Gold cider at Worthy Farm.
At around 3:30am on Sunday morning the deputy leader of the opposition posted a video of himself dancing the night away in a silent disco at the music festival, hours before the shadow cabinet began to unfold.
Ten hours ago Tom Watson was going for it in the silent disco tent. Can you imagine the scale of his hangover now. pic.twitter.com/MksQXCLyak— Jim Waterson (@jimwaterson) June 26, 2016
Later that day, Watson was spotted checking his phone as he waited for a train back to London.
Watson is no stranger to a festival hangover. The Labour MP is a regular at V festival, and was very impressed by rapper Tinie Tempah's set in 2011.
Tinie Tempah at the v-festival. He good but birmz grimez @ENRtwinz - to me they're the true voice if grime.— Tom Watson (@tom_watson) August 20, 2011
But Watson isn't all about silent discos and grime acts. In 2009 he declared himself a ska fan as he prepared to see seven-piece British band The Specials at V.
Can hardly contain my excitement. Soon to see the specials at the v festival. Too much too old.— Tom Watson (@tom_watson) August 22, 2009
Tom Watson's Westminster office has been approached for comment.
