The Paralympic Games were launched this week in Tokyo with the bold intention of changing the lives of the 1.2 billion people around the world who live with some form of disability.

But when disabled people are hidden from sight in many corners of the globe, can the legacy of these Paralympics really stretch beyond a fortnight of wonder in Japan?

We hear from Oksana Masters, a US Para-cyclist, rower and cross-country skier who has won medals at the summer and winter Games, and teenaged Ugandan swimmer Husnah Kukundakwe who is breaking boundaries in her homeland.

We also hear the views of GB Paralympic legend Tanni Grey-Thompson as we assess the potential for Tokyo 2020 to achieve lasting change.
