I thank my hon. Friend for his question and for the work that he has done over the years on this particular issue. I was pleased to be at the International Labour Organisation conference in Geneva last night to speak about our campaign against modern slavery, and to recognise that 90 countries have now signed up to the call for action against modern slavery which I launched in the United Nations. We see other countries following our legislative example—for example, the Dutch Senate recently, Australia, and President Buhari of Nigeria showing great leadership in sub-Saharan Africa on this issue. I am very pleased to see the impact that the Modern Slavery Act 2015 has had, such that a British citizen has been convicted in British courts for being part of a gang who trafficked Nigerian women to Germany, despite the fact that none of that crime touched the UK. She was a British citizen; she was prosecuted here, thanks to our Modern Slavery Act.
