A Zimbabwean government-run newspaper has accused an expert attached to a parliamentary committee heading the country’s controversial constitution making of spying for South African President Jacob Zuma. The allegations followed a week of heated exchanges between Pretoria and Harare over the timing of Zimbabwe’s next elections. President Robert Mugabe’s Zanu-PF party last week accused South Africa of gross interference after its Foreign Affairs minister Maite Nkoana-Mashabane insisted her government needed to see full reforms before elections are held.
