FORMER President Nelson Mandela has backed Britain’s policy towards Zimbabwe’s land grab crisis during a meeting with Prime Minister Tony Blair, Blair’s spokesman said on Wednesday. Blair used his hour of talks with Mandela to outline his Zimbabwe policy and concerns about violence which has left at least 18 people dead. “Nelson Mandela said he supported our approach and said he believed dialogue with Zimbabwe should continue and that President Thabo Mbeki had a key role to play in contact with Harare,” Blair’s spokesman said. Mandela and South African officials were not immediately available to give their assessment of the meeting.
