that day after nine hours. Bvudzijena, the police spokesman, rejected any suggestion that the police were trying to interfere in Tsvangirai's campaign; he explained the detention by saying that the police had wanted to determine whether a vehicle in Tsvangirai's motorcade had valid registration. According to Bvudzijena, the police had wanted to take only the driver of this vehicle to the police station to review the relevant documents, but that Tsvangirai and the rest of his entourage insisted on coming as well. On 22 June 2008, Tsvangirai announced at a press conference that he was withdrawing from the run-off, describing it as a "violent sham" and saying that his supporters risked being killed if they voted for him. He vowed that the MDC would ultimately prevail and that its victory could "only be delayed.". Shortly after making this announcement, Mr Tsvangirai sought refuge at the Dutch Embassy in Harare, citing concerns for his safety. He did not seek political asylum. Political negotiations On 22 July 2008, Tsvangirai and Mutambara met Mugabe face-to-face and shook hands with him for the first time in over a decade for negotiations in Harare, orchestrated by Mbeki, aiming for a settlement of electoral disputes that would share power between the MDC and the ZANU-PF at the executive level. This was followed by the beginning of clandestine negotiations between appointed emissaries from both parties in Pretoria. The media images of hands being shaken between the political rivals also set a stark contrast to the ongoing partisan violence taking place in both the rural and urban areas of Zimbabwe. At the end of the fourth day of negotiations, South African President and mediator to Zimbabwe, Thabo Mbeki, announced in Harare that Mugabe of Zanu-PF, Arthur Mutambara of MDC and Tsvangirai finally signed the power-sharing agreement – a "memorandum of understanding". Mbeki stated: An agreement has been reached on all items on the agenda ... [Mugabe, Tsvangirai, Mutambara] endorsed the document tonight, and signed it. The formal signing will be done on Monday 10 am. The document will be released then. The ceremony will be attended by SADC and other African regional and continental leaders. The leaders will spend the next few days constituting the inclusive government to be announced on Monday. The leaders will work very hard to mobilise support for the people to recover. We hope the world will assist so that this political agreement succeeds.
