How Big A Global Problem Is Tax Avoidance?

Today we look at tax and the lengths people go to avoid paying it. The New York Times has accused President Trump's father of potentially breaking the law in the way that he handed down his fortune to his family. Meanwhile in China, one of that country's biggest film stars, the actress Fan Bing Bing, has been fined the eye-watering sum of $129 million for tax evasion and other offences. Should there be a global push to crack down on tax avoidance and, if so, why hasn't it happened already?

Also on the programme, one of Saudi Arabia's most prominent journalists has disappeared in the Saudi Arabian embassy in Istanbul. We hear from one of Jamal Khashoggi's best friends, who is standing vigil outside the building. And today we launch our new, regular weekly report on climate change. We start off in Norway, a country committed to green energy which has grown rich on the back of oil. Can these two things be reconciled?
