Also in the programme: Vladimir Putin says exports of Russian gas will be stopped from Friday unless countries pay up in roubles, as US President Biden announces a record release of oil from the US's strategic reserve and a Turkish prosecutor asks to halt trial in the case of the murdered Saudi journalist Jamal Khashoggi.
