Beyond Belief: The Life and Mission of John Hume is a new musical drama about the Irish politician who was one of the architects of the Northern Ireland peace process. Marie-Louise Muir goes behind the scenes of the production, staged in Hume's home city of Derry, with its director, Kieran Griffiths. She follows his young company of actors rehearsing for a major production which will be streamed live globally on the 25th anniversary of the signing of the historic peace accord, the Good Friday Agreement.

Container ships are the monsters of the seas - the very biggest are almost half a kilometre long and piled high with up to 20,000 huge boxes. At any one time, there are tens of thousands of these floating cities on the move, many unable even to dock at local ports. It’s our relentless demand for more and cheaper stuff that drives the industry. We meet the British salvage man who’s making millions from the boxes that get left behind, lost or abandoned - yet another example of how invisible the world of shipping is, even though the whole planet depends on it.Image: Jake Slinn, founder of JS Global, at Felixstowe docks

Shipping has long been one of the most opaque of global industries. Now many operations in the oil sector, which accounts for nearly a third of all seaborne trade, have become still more secretive, following the West's imposition of sanctions on Russian oil. A new "dark fleet" of ageing tankers with obscure ownership, flying flags of convenience, has been formed to avoid the sanctions - and there has been a big increase in risky ship-to-ship transfers at sea, which make it easier to disguise the oil's origin. The Laconian Gulf in southern Greece is a major hub for such transfers, and locals now fear any accident could cause major environmental damage in an area which depends on tourism and fishing. Tim Whewell witnesses the operations close-up, and talks to campaigners who believe the influence of powerful shipowners makes local authorities turn a blind eye to possible dangers. Who is responsible for policing the operations of ships in international waters? And where is the oil going? The war in Ukraine has led to a major reshuffling of trade flows, as Asia becomes an ever bigger market for Russian crude.Presenter: Tim Whewell Producer: Monica Whitlock
