So as I understand it, this lady was possibly a member of (or associated with) a group that is proscribed by the UKIP e.g. EDL, BNP, Britain First etc and was therefore in breach of UKIP membership rules.
My view on this is that if this was some other party, they would either have covered it up or stretched things out for ages until the matter was forgotten or the person would eventually resign - but it wouldn't be a quick thing.
So I say well done UKIP for acting so fast to be shot of yet another loony; I'm sure there are still more to go but this is a good sign.
Looks to me like UKIP are doing what they can to distance themselves from association with racists, homophobes and other extremists.
The UK Independence Party says it has expelled one of its councillors "for bringing the party into disrepute".
Rozanne Duncan is understood to have used highly racially offensive language during filming for a BBC documentary to be broadcast in February.
The party did not give the reasons for Ms Duncan's expulsion but said she had 28 days to appeal.
She sits on Thanet District Council in Kent, where she was UKIP group deputy leader.
