We hear why Ukraine is concerned by a US-German deal over the Nord Stream 2 gas pipeline. The pipeline will bring gas from Russia to Germany, bypassing Ukraine, and Thierry Bros of the Paris Institute of International Studies explains the background. And we get reaction to the new agreement between the US and Germany aimed at preventing Russia from using the pipeline to exert political leverage over Europe, from Ukrainian politician Hanna Hopko, who previously chaired the parliamentary committee on foreign affairs in Kiev. Also in the programme, the Saudi Aramco oil giant has been hacked, and now faces demands to pay a ransom to avoid stolen data being released. We find out more from Chris Kubecka, who is a computer security researcher who got Saudi Aramco's network back up and running after a cyber attack in 2012. A day before the opening ceremony of the Tokyo Olympics, the BBC's Sasha Twining reports on what the event has cost Japan, and how much of that money it is likely to be able to recoup. Plus, we hear from Caroline Casey, who has successfully persuaded the chief executives of 500 major corporations to commit their boards to disability inclusion, and is discussing the achievement at this year's One Young World Summit.
