Cost of period products has risen and campaigners say saving is not being passed on by retailers

The Treasury is analysing whether the removal of the “tampon tax” – trumpeted last week by Rishi Sunak as one of the benefits of Brexit – has helped lower prices at all, amid concerns the saving is not being passed on by retailers to women.

Responding to a written question from the Labour MP Ruth Cadbury, the government said a tax reduction was able to “contribute to the conditions for price reductions” and it was “looking into whether this important zero-rating is being passed on by retailers to women as intended”.
