Zeinab Badawi speaks to Rwandan politician Frank Habineza who founded the opposition Democratic Green Party of Rwanda in 2009. He wants President Paul Kagame, who has been in power for more than 20 years, to stand down at the next presidential elections in 2017. Rwanda is still in the process of recovering from the genocide of the mid-1990s, and the government has been praised for its success in alleviating poverty and bringing about reconciliation. But Habineza thinks it is time for a change and has been critical of government policy. What can he offer a nation that has been so scarred by tragedy?
