A member of the European Parliament (MEP) has vowed she will fight a ban on her standing for the party at the next general election.
Nikki Sinclaire recently quit the party's European Parliament grouping and has been accused of breaking its rules, the BBC reports.
She resigned from her role, accusing colleagues of harbouring "extremist views".
Speaking to BBC2's Daily Politics show, she claimed that despite not being subject to any disciplinary procedures, she had been informed by party officials that she could not use its logo or name in future elections.
Ms Sinclaire, who is one of six MEPs from the West Midlands region elected in June 2009, said she had been "very hurt" by comments made by the party's leader in Brussels Nigel Farage.
Recently, he said he took a "dim view" of her decision to quit the Europe of Freedom and Democracy grouping.
Paul Daniels, who is an employment partner at Russell Jones & Walker and has been instructed to advise Ms Sinclair, remarked: "The treatment of Ms Sinclair seems most inappropriate. We look forward to assisting her in this matter."
