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...
