Jean Ping has promised political reforms in Gabon if he becomes president.
The former chairperson of the African Union officially joined the Gabon Progress Party (GPP) in which he is expected to challenge president Ali Bongo Ondimba in the August 27 elections.
Ping had previously been linked to other political parties but eventually joined the GPP, where he said he felt at home.
Gabon’s current constitution states that the president is elected for a seven-year term that is renewable several times.
He also called for the need to establish a Truth and Justice Reconciliation Commission like the one in South Africa to reconcile the Gabonese people.
