A Liberal Party candidate running in this week's Victorian election has been sacked for his reported involvement in bringing a porn star-turned-Bollywood actress to Melbourne.

Nitin Gursahani was standing for the seat of Thomastown before it was revealed he was helping promote the Melbourne tour of Indian actress Sunny Leone.

In a statement, the Liberal Party said Mr Gursahani failed to disclose his connection with the tour.

"He was never forthcoming during the application process and never disclosed this information," a spokesman said.

"This material does not reflect the values that underpin our party.

"He is no longer the endorsed candidate for Thomastown."

According to Ms Leone's website, the actress "is rated one of the top porn stars in the world".

She is scheduled to appear at events in Melbourne this week and Mr Gursahani's family business is believed to be sponsoring the tour.

Premier Denis Napthine said he had only heard of the sacking on Saturday afternoon and it was a matter for the Liberal Party's administration.

"Labor's replaced five candidates in the last 12 to 18 months. These issues arise from time to time in an election period," he said.

"The Liberal Party, when these things arise, deal with it efficiently, effectively and strongly."

Labor spokesman Martin Pakula said with two Liberal candidates sacked within a week, it appeared the party was descending into chaos and disarray.

But the Australian Sex Party, which has a number of candidates contesting the Victorian election, criticised the sacking.

"Do we have to remind Liberal and Labor parties that sex workers are not people to be ashamed of?", it said on Twitter.
