Jeremy Corbyn Favourites Embarrassing #PigGate Tweet Mentioning Diane Abbott

Jeremy Corbyn -- or more likely the person who runs his official Twitter account -- has hurriedly undone a favourite of a tweet that unfavourably compared the #PigGate affair with new shadow minister Diane Abbott.

Widespread discussion was sparked after lurid accusations of debauched behaviour on the part of David Cameron were made in a book serialised in the Daily Mail newspaper.

As part of the fervour, a chauvinistic tweet was directed at Corbyn's MP account on the social network.

Twitter user Xyzanic wrote: "Which is worse? F**king a pig or f**king Diane Abbott?"

The tweet appeared temporarily at the top of Corbyn's favourites

But rather than ignoring the message -- or reporting it to Twitter -- Corbyn's account appears to have 'favourited' the message by mistake.

The favourite was quickly deleted.

It comes a week after claims that the two shadow cabinet colleagues once had a romantic relationship.

But unfortunately, eagle-eyed people on Twitter soon caught on...

But we perhaps shouldn't read too much into the slip.

Corbyn appears to have favourited a tweet by himself before...
