Natalie Collins was speaking after David Cameron announced possible plans to force companies to publish the average earnings of both sexes.
He wrote in The Times newspaper: "Under the coalition government, the gender pay gap narrowed. For full-time workers over 40, it is almost zero.
"But overall, a woman still earns just 80p for every £1 earned by a man. That is a scandal - and I'm determined to close the gap."
However Ms Collins has questioned the integrity of the government's intentions, referring to a previous piece of legislation in the last Parliament which would've forced companies to reveal their gender pay gap, which the Conservatives refused to support whilst in coalition.
She also said that the Conservative's austerity measures were hitting women three times harder than men, and said she found it disturbing that child tax credits were limited to only two children - unless the woman was found to have been raped.
Ms Collins told Premier's News Hour: "The austerity measures are hitting women three times harder than men, and so we've got to be thinking much more broadly about the impact of the Conservative policies on women, rather than thinking just about this specific measure [on gender pay].
"Even up to last year the Conservatives in the coalition ditched Section 78, which would've done exactly this [reveal companies' gender pay gaps], and so I think there's some concerns that I have around the integrity with which this is being brought forth... a very surface-level measure that actually isn't really going to make a difference to the majority of women.
"I mean one of the policies, not paying tax credits for a third or further children but writing in some policy which means that if a woman is raped... then... we'll give her third child tax credits, what sort of government creates those sorts of policies?"
