President Kgalema Motlanthe on Wednesday rejected renewed calls for the Presidency to establish a commission of inquiry on the arms deal.

"Government has always maintained that if anyone has information implicating individuals in the arms deal, then that person should forward such information to law enforcement agencies," his spokesperson Thabo Masebe told journalists in Cape Town.

The president was convinced that a commission of inquiry would not be an appropriate tool to investigate alleged criminal activities during the arms deals.

"There is already an investigation in some of these matters and we are confident that our law enforcement agencies are capable of handling any allegations pertaining to the arms deal," Masebe said.

Archbishop Desmond Tutu and former president FW de Klerk had written to Motlanthe requesting he establish an independent commission to probe the arms deal.

Masebe said a letter would be sent to Tutu and De Klerk on Wednesday informing them about Motlanthe's decision. The letter would be made public. Tutu and de Klerk's call received support from clergymen, academics, authors, activists and politicians.
