Zambia's ex-President Rupiah Banda pleads not guilty.

 
The charges relate to an oil deal signed with a Nigerian company, which prosecutors say was meant to benefit Mr Banda and his family.
"No my Lord, I deny the charge," Mr Banda told the court, AFP reports.
The ex-president says the charges are part of a political witch-hunt against him and his allies.
After three years in power, he lost the 2011 election to Michael Sata.
He was arrested and questioned for nearly three hours before being freed on bail on Monday.
Earlier this month the 76-year-old was stripped of presidential immunity.
He is due back in court next month to answer further allegations when his trial starts.
The new government has launched a high-profile investigation into allegations of corruption by members of Mr Banda's administration.
One former minister has been found guilty and is appealing against his conviction.
