Zimbabwe's vice president Constantino Chiwenga who also doubles as the country's war veterans and defence minister has reportedly increased retirement age of senior army officials in a bid to maintain "liberation war veterans stranglehold of the army". According to NewsDay, Chiwenga increased the current retirement age of 65 years to 70 years and has "classified them as 'specialist military personnel' as the country glides towards a military state".The former military chief announced the changes in a government gazette last week. Analysts have described the move as a strategic attempt to retain the war veteran element in the army whose members might be approaching retirement age, said the report. The report came a week after the southern African country held its first elections since former veteran ruler Robert Mugabe was deposed. * To follow the latest on the Zimbabwe elections SIGN UP TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
