As the global elite meet for the World Economic Forum in Davos, two of the main issues being discussed include uncertainty facing the global economy and climate change. Also in the programme: Zimbabwe’s President Emmerson Mnangagwa has responded to the violence and protests on the country’s streets, and it’s the 50th anniversary of the Cairo International Book Fair- which is the biggest and oldest in the Arab world.
