Leaders from members of the Francophonie organisation will gather in Kinshasa next week for the 14th summit of the group of French-speaking countries. However, as delegates prepare to travel to the Democratic Republic of Congo for the event, officials from one member country have begun making moves towards membership of a rival English-speaking organisation, the Commonwealth. Burundi is looking to emulate its Rwandan neighbour by joining the club of mainly former British colonies. To find out why Burundi is turning its back on the Francophonie organisation and whether other African countries might follow suit, RFI spoke to Philip Murphy, the head of the Institute for Commonwealth Studies at the University of London.
