Johannesburg: Jacob Zuma, ANC leader, started a final attempt in South Africa's highest court on Tuesday to stop seized documents used as evidence against him at a corruption trial that may end his chance of becoming a president.

Zuma is indicted of accepting hundreds of thousands of dollars from French arms manufacturer and his previous financial advisor in the form of bribes.

On Tuesday, Zuma and his legal team appeared in the Constitutional Court, requesting leave to appeal against prosecutors' searches and confiscation of documents in 2005.

The corruption trial against Zuma is going to be initiated in August and will probably decide if he is going to succeed President Thabo Mbeki.

Zuma said he will step down if found guilty, maintained that the charges against him are politically motivated.
