Derby North MP Amanda Solloway has spoken of the "embarrassment and shame" she felt as a teenager when she was forced to use toilet paper or newspaper during her periods.
Raising the issue of period poverty during Prime Minister's Questions, the Tory MP said: "We couldn't afford sanitary products and I was forced to use toilet paper or, when we didn't have that, newspaper."
From Monday, the government introduced a scheme to allow schools and colleges to order free sanitary products.
The MP added: "Would the prime minister acknowledge the work of Amika George, the founder of the Free Periods campaign group, that means no young woman of school age in this country should ever have to feel the shame I felt and remember all those years ago?"
In response, Boris Johnson said: "Free period products are to be made available to all schools and colleges in England so that we can ensure that no young person's education is disrupted by their period.
"I'd like to pay particular tribute to the work of Amika George, who has done so much to bring about change."
