A Liberal candidate has resigned after criticising a woman who said her husband had raped her, saying the husband was the "real victim".

A spokesman for the Victorian Division of the Liberal Party said Scullin candidate Gurpal Singh was asked to step down after a series of offensive Facebook posts were made public.

"Based on new information that has come to light, Mr Gurpal Singh has been asked to resign as the candidate for Scullin. Mr Singh sincerely apologises for his previous comments and has tendered his resignation," the spokesman said.

Mr Singh is the seventh Victorian Liberal candidate to be disendorsed by the party this federal election.

Mr Singh had previously linked same-sex marriage with paedophilia.
