This isn't because the Tories are pro women but because it was the EU that made the UK put VAT on sanitory products. The previous government did reduce it from 15%(?) to the minumum the EU would allow and promised to put the into the Tampon Tax Fund for women's groups. (Which as we know went to large conglomorates and not to frontline services).
So wonder if the promised money to make up for the lost VAT will be found or in fact argued that it should got into an initiative to provide free products in schools.
(Although in fact the Tories have always funded Rape Crisis Helpline to a far larger extent than Labour.)
