Russia's currency, the rouble, has recovered from the extreme lows seen in recent weeks and is now trading at levels that haven't been seen since before Russia invaded Ukraine in February. Elina Ribakova, Deputy Chief Economist at the Institute of International Finance, explains why. At the same time EU sanctions on Russian coal are looming, and we ask Monika Schnitzer of the German Council of Economic Experts how that might impact things. We also speak to Maksim Timchenko, chief executive of Ukraine's largest private power producer, DTEK, about the challenge of keeping supplies flowing during a war. Also in the programme, Theo Leggett heads to northeast France for a special report on high youth unemployment in the region. And finally, a shirt worn by the Argentinian football star Diego Maradona during a famous 1986 World Cup match is now up for auction. Sotheby's auction house hopes it will bring in a staggering $5 million. Argentinian sports writer Marcela Mora y Araujo tells us if she thinks the shirt will fetch such a sum.
