Editor's note

Zimbabwe is on the edge. To help prevent the chaos from escalating even further, President Emmerson Mnangagwa - and those he can rally behind him in the ruling Zanu-PF - need urgently to take steps towards forming a government of national unity as has been done before in the country, writes Tapiwa Chagonda.

Nigerians are set to head to the polls early next month, and campaigning is in full swing. One of the biggest promises President Muhammadu Buhari made when he came to power in 2015 was that he would deal with threats to the country’s security. But, argues Olayinka Ajala, Buhari has failed to live up to those promises - and that may cost him a second term.
