Human Settlements Minister Tokyo Sexwale had put one of his private jets on standby for his hospitalised deputy, Zou Kota-Fredericks, his office said on Thursday.

Kota-Fredericks was seriously injured in a head-on collision 20km from Leeu-Gamka near Beaufort West on November 1.

Sexwale's special advisor Chris Vick said her condition had improved slightly since the accident, but she remains in the intensive care unit.

Sexwale, who would visit her later on Thursday, hoped she would soon be well enough to be moved to Cape Town, so she could be closer to her family.

Sexwale had put "one of his private jets" on standby should it be necessary to airlift her closer to home.
