30 seconds to on air! OK, and you are just here. Good most, so far the better. Now, an extraordinary story about a young man who many years ago visited Prague. 40,000 there were thousands of refugees that the mercy of Hitler's imminent invasion. Do you ever think about the children and what happened to them? I'm sorry. I'm sorry. They have made us some stories. That's really not about me. We are working to evacuate these children by train to safety in Britain. Why are you doing this, Mr. Winton? Because I may be able to do something about it, I must. Go! No! Nikky, you must know we cannot save them all. You have to forgive yourself that. I've started so I have to finish it. We cannot let these people down. It is incredible what you achieved. We are doing as much as we can. We have a lot of faith in ordinary people. Because I'm an ordinary person. Save one life, save the world. I'm forgiving about how much children are we speaking about? Can I ask, is there anyone in the audience tonight who owes their life to Niklas Winton? Thank you.
