The late night activities of Gavin Barwell, Theresa May’s chief of staff in Number 10, are usually limited to tweeting from Nando’s. On Monday night however, it appears he was choking the chicken rather than eating it.

Barwell’s Twitter account replied to a pornographic tweet featuring two ‘teen schoolgirls’ and their ‘mom’, as well as a second video from the niche website Blacked.com. Guido has analysed the tweets and determined it is impossible that Barwell was hacked or clicked on a funny link. The only way he could have tweeted a reply featuring these handles – which were tagged into the original porn tweet – is if he was viewing the tweet in question. The porn account’s name is “Twinkystar“, and Gavin was viewing it on his Android device at 9:21pm. At least he wasn’t doing it in the office, right Gavin?

UPDATE: Barwell has now deleted the tweet, proving he does have access to his account.

UPDATE II: Told Barwell was not in Downing Street when he sent porn reply (phew!). No. 10 source: “Gavin Barwell replied to this tweet, which was in his timeline, in error. He has deleted the reply and regrets the embarrassment this has caused.”
