Zimbabwean President Emmerson Mnangagwa this week took his election campaign to his predecessor Robert Mugabe's hometown, Chinhoyi, but he completely "did not mention his name", says a report. According to Voice of America (VOA), during his slightly more than 1 hour long speech, Mnangagwa did not mention the former president's name. He instead appealed for unity within the ruling Zanu-PF party. Mnangagwa said that the country was only going to prosper under his Zanu-PF banner. Reporting from the same event, the state-owned Herald newspaper quoted Mnangagwa as saying that his government was "revamping the economy to ensure the country becomes the Jewel of Africa through sheer industry".Since assuming office in November last year, the new administration has locked in over $16 billion in investment commitments in addition to recovering over $850million out of the $1.4 billion that was illegally externalised by corporates and individuals over the years, the report said. Zimbabweans are set to go to the polls on July 30.At least 5.5 million registered voters are expected to cast their ballots. * Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
