Thanks to floor-crossing, the African National Congress (ANC) has at last secured a clear two-thirds majority in the Morkel family. The decisive moment came on Wednesday when the last of the Morkel brothers, Craig, joined the party. But the patriarch, former premier Gerald Morkel, has no intention of following in his sons' footsteps.

South Africa's ruling African National Congress (ANC) is set to entrench its political dominance with a 15-day window period opening this week to allow elected officials to swap party allegiance without losing their seats. The opposition is likely to be further fragmented as representatives at the national, provincial and municipal government levels are free to cross the floor.
