By MacDonald Dzirutwe HARARE, Oct 27 (Reuters) - Zimbabwe President Robert Mugabe accused the main opposition party on Saturday of making false allegations of government violence to derail reconciliation talks. The Movement for Democratic Change (MDC) and the ruling ZANU-PF party are in talks mediated by South African President Thabo Mbeki as part of regional efforts to end Zimbabwe's deepening economic crisis and promote political reconciliation. "From out of the blue, his (Tsvangirai's) party is making unsubstantiated reports of growing and sustained politically motivated violence being perpetrated against its supporters," he told members of the ZANU-PF central committee, according to the official Herald newspaper. "It is, therefore, unacceptable that in light of the positive strides we have made, others like Morgan Tsvangirai, who is always the joker, find it necessary to frustrate this fledgling process." The MDC, led by Tsvangirai, said last week the government was heightening a violent crackdown against its supporters but said it would not walk away from the talks. On Wednesday, Zimbabwean Home Affairs Minister Kembo Mohadi met MDC officials who chronicled cases of alleged politically motivated violence by the police, army, intelligence services and Mugabe's supporters. Mohadi promised to investigate the claims. "Let it be known that we will not take kindly to 'cry wolf' boys, desperately pretending to be politicians and seeking to embellish their faltering ambitions through falsehoods," Mugabe said. Mugabe has in the past accused the MDC of being puppets of his critics in Britain and the United States. Zimbabwe is due to hold parliamentary and presidential elections next year. Former colonial ruler Britain and the U.S. have led a campaign to isolate Mugabe over charges of human rights abuses and rigging elections, charges the Zimbabwe leader denies. Mugabe, 83 and in power since independence in 1980, says Western powers are punishing his government for seizing white-owned farms to resettle blacks and that this had sparked an economic crisis that has left Zimbabweans grappling with the world's highest inflation rate. In March, police were alleged to have beaten opposition and civic group leaders, including Tsvangirai, in custody after they attempted to hold a banned prayer rally in Harare. The government accused the MDC of starting a terror campaign via a spate of petrol bombings against police and ZANU-PF targets. Although dozens of MDC members were detained for months, they were released without charge.
