Mr Waititu was at pains to explain how he sold a parcel of land to the contractor before he officially acquired it.
But the prosecution took issue with the power of attorney, saying Mr Waititu sold the land before he acquired it.
Former Kiambu Governor Ferdinand Waititu, his wife Susan Wangari, and a contractor implicated in a Sh588 million corruption case on Tuesday presented their sworn evidences in court.
Mr Waititu, Ms Wangari and Mr Charles Chege, the proprietor of Testimony Enterprises Limited, testified before Chief Magistrate Thomas Nzioki at the Milimani Law Courts and were cross-examined by the prosecuting counsel, Ms Faith Mwila.
