We hear from the BBC's Mohammud Ali in the Kenyan capital Nairobi and Ollo Sib who works for the UN World Food Programme in Senegal's capital Dakar. Sri Lanka has been hit hard by the surge in global inflation and its reserves of foreign currencies - used to pay for imports - are dwindling. So to preserve its foreign exchange, Colombo has just increased import taxes on a wide range of goods. We get more details from Dimuthu Attanayake, a journalist in Sri Lanka's capital Colombo. The nations that make up the oil cartel Opec - along with Russia - have just said they'll increase the amount of oil they produce over the next couple of months. We hear more from Amena Bakr, chief Opec correspondent for Energy Intelligence. The UK is now in the midst of a four-day long weekend to mark Queen Elizabeth the Second's Platinum Jubilee, celebrating 70 years on the throne.
