The financial secretary is to seek clarity on a European court ruling which could see the end of lower car insurance premiums for women.
Mark Hoban said the ruling on sex discrimination in insurance "goes against the grain" of a common-sense approach to equality.
He said he would consult on changing UK equality laws to comply with the decision by the European Court of Justice.
He added that the UK Government considered the judgment only applied to new contracts for insurance and related financial services entered into on or after December 21, 2012.
Mr Hoban also said that he would seek "legal certainty" about the court's ruling and also press for an amendment to the European Commission's Gender Directive.
The court's decision would preventcar insurance premiums being determined by gender.
The Association of British Insurers estimates that women aged under 25 could see a 25% increase in motor insurance.
