Zeinab Badawi speaks to the vice president of the small southern African state of Malawi, Saulos Chilima - a former business executive turned politician. Mr Chilima was President Mutharika's running mate in the elections in 2014. Now he has left the ruling Democratic Progressive Party (DPP) and says he will run against him in the presidential elections next year to - as he puts it - 'save the country from destruction and corruption'.
