Human Trafficking and Modern Slavery

My hon. Friend is making a fantastic speech on important issues. I wonder whether I might lift his gaze to the global situation. The International Labour Organisation estimates that there are 50 million people in modern slavery, a large number of whom are in south and south-east Asia and involved in textiles, construction and fishing. Many of them will never leave, for example, the same brick kiln . Does my hon. Friend agree that it is incumbent on the UK Government to challenge Governments in the countries concerned to look at what is happening, and to challenge businesses here to ensure that goods produced in this way do not end up in UK supply chains? Does he agree that we all have a role to play in that important work?
