Independent Democrats' leader Patricia de Lille says South Africa should have a separate election for the president of the country.
This would prevent the "fight for power" currently being waged in the ANC, De Lille's said to Sowetan yesterday after the Independent Democrats (ID) conference at the University of the Western Cape, where she was elected unopposed as party president.
"We feel that if we elect the president directly it will contribute towards nation-building and reconciliation," she said.
"South Africans will feel it is their president, serving all of us.
"Members expressed concerns about the succession debate which overshadowed the ANC's policy conference. It was all about power and personalities.
"The country can't afford the division and the fight for power.
"It will mean a constitutional amendment, but the ID will start campaigning to have the president elected directly," she said.
De Lille said her party supported Van Zyl Slabbert's proposals to change the electoral system to make public representatives more accountable to voters.
She said she had raised the issue in parliament several times with Home Affairs Minister Nosiviwe Mapisa-Nqakula, but no action had been taken.
De Lille also called for a crime summit to be convened urgently and said she had written to the speaker of the national assembly to implement a decision announced on this by President Thabo Mbeki.
