On Friday Iranian authorities seized a British-flagged tanker in the Gulf. Iran said the vessel was "violating international maritime rules". We’ll hear the latest on the tanker’s status, discuss why it wasn’t given Royal Navy protection, and find out what’s happened to the Iranian tanker that was detained off the coast of Gibraltar earlier in the month – a move Iran warned the UK would face retaliation for. Also in the programme: it’s 50 years since Neil Armstrong and Buzz Aldrin became the first people to set foot on the Moon; and Germany pays tribute to Claus von Stauffenberg and others who tried, 75 years ago, to assassinate Adolf Hitler.
