A MUCH-hyped $60,000 interview with a prostitute who claims to have slept with Craig Thomson may never be broadcast.

In a rare occasion of good news for the suspended Labor MP, the Nine Network's A Current Affair announced it would hold off airing the interview.

But it denied having cold feet over broadcasting the allegations made by the former hooker during a lengthy interview. Instead, the high-rating program said it wanted to ensure her evidence did not interfere with a police check of Mr Thomson, accused of using union funds for prostitutes.

In a statement, producers said they had "supplied evidentiary material in our possession, resulting from our inquiries" to Victorian police for their investigation.

"We now await the outcome of the police investigation before pursuing the story any further," ACA said.

Last week ACA executive producer Grant Williams fronted Mr Thomson in his parliamentary office with details of the woman's evidence, prompting the MP to accuse the broadcaster of "grubby" journalism and threaten legal action against Nine.

Mr Thomson has denied using any Health Services Union credit cards to pay for the services of prostitutes.

The former prostitute, now working in the horseracing industry and living in northern NSW, has signed a statutory declaration.
