Carina Trimingham is to appeal against a privacy judgment in favour of the Daily Mail and Mail on Sunday which said may become a 'blueprint for bullies and bigots".
She today lost her legal action for harassment and breach of privacy over a long series of articles in the Daily Mail and Mail on Sunday about her relationship with married former cabinet minister Chris Huhne – many of which made reference to her bisexuality.
Trimingham, who is understood to be insured, will have to pay Associated Newspapers' £410,000 legal costs.
Mr Justice Tugenhat said in his judgment today: 'Ms Trimingham was not the purely private figure she claims to be. Her reasonable expectation of privacy has become limited."
He also said: 'Insulting and offensive speech is protected by the right of freedom of expression".
Outside court, Ms Trimingham said: "I am extremely disappointed by this judgment. There is a ray of light, however.
"Thankfully, the court has accepted today that repeated mocking of a person by a national newspaper by reference to their sexual orientation would almost inevitably be so oppressive as to amount to harassment.
"However, the court did not appreciate that when newspapers make repeated irrelevant references to sexuality - particularly in the context of pejorative and stereotypical references to appearance - it amounts to the same type of mocking which the court has confirmed is unacceptable.
"This is confused, and I think wrong. I am very concerned that this judgment may become a blueprint for bullies and bigots. I intend to appeal."
