Maria Miller, Conservative MP for Basingstoke and Chair of the Equalities Select Committee is to undertake a review of a flagship piece of legislation that her government introduced - The Modern Day Slavery Act, which came into force in 2015. Women MPs across party working together, were instrumental in pointing to the growing numbers of trafficked women working in nail bars, domestic service, massage parlours and in prostitution itself. The economic and social costs of modern slavery are estimated to be in the region of 4.3 billion pounds a year. Miller told Sones that we should not have people who are subject to slavery and should not have people who their rights withheld.
