Contest for UK's next PM starts after Truss resigns

Liz Truss's resignation means the UK must find its third PM this year. The BBC's Rob Watson brings us up to date with all the reaction, and tells us what the next steps will be in choosing her successor. We also get reaction from UK business, and hear from construction firm The Deeley Group what policies it wants from the new PM. And Cary Leahey, economist at the University of Columbia, tells us how international markets have reacted to Truss's resignation. In Nigeria, inflation has reached 20.7 percent - the highest rate for 17 years. Babajide Ogunsanwo runs a business in the capital Lagos and tells us how people there are coping with higher prices. And it's estimated that a third of the world's population don't have access to the internet. We hear from farmers in Kenya who are using the internet and social media apps to grow their business, and also from the head of the UN's development programme, Achim Steiner, about how it is making digital connectivity a priority.
