With people still left guessing as to whether he intends holding formal talks with his country's opposition, Zimbabwean President Robert Mugabe added a new dimension to the drama this weekend when he was allegedly rushed to South Africa after collapsing at his home in Harare. The speculation about the Zimbabwean leader comes at the tail end of a week of debate about South Africa's role in helping to resolve the political situation in Zimbabwe. On Thursday South African President Thabo Mbeki said Mugabe's ruling ZANU-PF party had agreed to enter into formal talks with the opposition Movement for Democratic Change (MDC) on resolving Zimbabwe's long-running political crisis. But the MDC's Secretary for Information and Publicity, Paul Themba Nyathi, told IPS that his party was extremely sceptical about "the nature of Mugabe's commitment to a process of dialogue".
