According to reports, more than R200-million of taxpayers' money has been set aside for upgrading the property.

Zille, accompanied by other DA officials, will look at the roads surrounding the property and attempt to enter the compound.

It has been reported that the president's private home will feature underground bunkers, a clinic, a fire station, special quarters for the police and a helipad.

It is estimated that the upgrading will cost between R203-million and R238-million, with the president contributing only R10-million.

The Department of Public Works has repeatedly defended the upgrading.

DA spokesman Mmusi Maimane yesterday said: "It's important to contrast the [more than] R200-million spent on the building of the president's mansion against the non-delivery of textbooks, and that our country is the lowest [scoring] in maths and science [exams]."

Asked if the DA team will enter Zuma's homestead, Maimane said: "We will see how we go."

Public Protector Thuli Madonsela will investigate the development of a R2-billion town in the president's village of Nkandla.

But Madonsela's investigation will not include the upgrading of the Zuma homestead.
