In an advert published in local paper The Rotherham Record to wish the locals a Merry Christmas, the eurosceptic party's local branch appealed for people to 'say no to the UK!'
Unless a splinter group has emerged with very different aims, we think it was meant to say 'say no to the EU'.
It wasn't clear whether the typo was the mistake was the fault of the newspaper or the party. Unless, confusingly, it is not a mistake and Ukip is now backing Scottish independence.
A tweet from local Labour councillor Chris Read was retweeted more than 1,000 times.

Rotherham UKIP want you to 'SAY NO TO THE UK!'. Freudian slip or lack of copyediting? pic.twitter.com/9IkWlSeg1N— GY Labour (@gylabour) December 20, 2014
Ukip had not replied to a request for comment as this article went live.
Rotherham is a key target ground for the party in the wake of the extraordinarily damning report that concluded 1,400 children were abused by gangs there between 1997 and 2013.
This did the Labour-controlled council a lot of damage and recent Ukip surges in council elections have raised the party's hopes of ousting Sarah Champion, the South Yorkshire town's Labour MP in 2015.Suggest a correction
