A sexism row has erupted in Witney as it emerges a local shopping centre charges women - but not men - to use public toilets.
Marriott's Walk shopping centre also charges disabled people for the use of its facilities.
The shopping centre, in David Cameron's Oxfordshire constituency, means that while the former Prime Minister would be entitled to use its services free of charge, his wife Samantha would have to pay 20p.
Locals have branded the system unfair and sexist after it came to light that women and disabled people have to pay to use a cubicle but men are able to use the urinals for nothing.
Councillors have joined the campaign to either make the facilities in Marriott's Walk free for all, or to level things up and charge men the same as women.
Grandmother-of-four Maggie Newton, 57, is leader of Doing It Together To Overcome, a charity which supports disabled and vulnerable people in and around the Witney area.
When she first heard about the charge she was stunned, and raised it at a recent meeting for locals.
"I just can't believe there is still this level of discrimination and inequality in this day and age. Men have got a choice, but women and the disabled don't.
"What I'm saying is keep it equal. At the moment women and disabled people are covering the cost of cleaning the men's toilets. We don't want to pay to clean the men's toilets. It all seems a bit archaic."
Witney's mayor Chris Holliday said "Men don't pay, but when you want a pee, you want a pee whether you're a man or a woman. It is a bit unfair."
Laura Price, the county councillor for Witney, said the 20p charge hits people who may need toilet facilities the most and it should be scrapped.
"Unfortunately, if you're old, have a disability, a mental health problem or learning difficulty, or if you're the parent of young children, you're getting penalised.
"I think when you think about who this charge has an impact on versus who doesn't really need to think about it, you realise that actually you're putting barriers there for people who have enough barriers in their life."
The centre has not responded to requests for comment.
The discrepancy in the shopping centre's system may go back to outdated legislation from the 1936 Public Health Act that allowed local authorities to charge for cubicles but not urinals.
However, councils have been able to charge for urinals since an amendment in the 2008 Sex Discrimination Act came into force.
Jane Doughty, district councillor for Witney South said of the Marriott centre: "I think it's completely disgraceful. It isn't even just about female or male you're looking at disabled people as well.
"I've got no idea why [this is the case] the people need to talk to are the managers. They need to answer why - men can spend just as long in there as a female I can't believe for one minute that's justified."
Duncan Enright, councillor for Witney East said: "I was unaware of it. They are tenants because it's owned by the District Council. It should be free for everyone, it's ridiculous.
"It seems very odd that it should be organised that way. Toilets across the country have been closing because councils have been making cuts maybe it's a symptom of that. I can't see any justification for it."
However, a spokeswoman for Oxfordshire district council said they had no involvement in the funding of the toilet.
