Nottinghamshire's only British National Party councillor has been expelled from the party.
The BNP said Sadie Graham was thrown out for "gross misconduct".
On its website the BNP said Sadie Graham and another expelled official, Kenny Smith, had criticised the leadership of the party.
Ms Graham, who was elected for the Brinsley ward on Broxtowe Borough Council in May's elections, was not available for comment.
A BNP spokesman said: "This is an internal matter but we put it on our website because we felt members should know.
"In this particular circumstance it was a decision we simply had to take."
A Broxtowe council spokeswoman said Ms Graham remained an elected member and the authority was waiting for her to advise the council of the implications of her expulsion from the BNP.
