The Universal Credit benefits system is forcing some women to turn to sex work, charities say.
The BBC has spoken to five charities and organisations in England who say there are increasing numbers of women on the credit (UC) in this position.
Frank Field, MP for Birkenhead, also told MPs in October "some women have taken to the red-light district for the first time" as a result of UC.
The government said: "No-one has to face hardship on Universal Credit."
"Julie", from Merseyside, never thought she would have to turn to sex work.
But an eight-week wait for the single mum's first payment after transferring from her previous benefits left her "desperate", so when she was offered £30 for sex she took it.
"I'm ashamed to admit, I have slept with a guy for money", said Julie, who asked for her real name not to be used.
"It's something I never ever thought I would be ever capable of doing. I just didn't think it was in me as a person.
"So I'm, like, very disappointed in myself and ashamed of myself.
"I had to use food banks. I've never been in that situation in my life. I've really struggled."
When Mr Field made his comments in the Commons, then Work and Pensions Secretary Esther McVey said work needed to be done to help them.
"Perhaps [Mr Field] could tell these ladies and the work coaches that now we have got record job vacancies - 830,000 job vacancies - and perhaps there are other jobs on offer," she said.
But Mr Field told the BBC he had received no contact from the government since raising the issue in parliament, following UC's introduction in his constituency in November 2017.
"[Women turning to sex work is] an absolute indictment of welfare reform… it seems that you couldn't get a worse result," he said. "
