Zambia's newly elected President Michael Sata has dismissed the head of the country's anti-corruption watchdog.
A presidential statement said Godfrey Kayukwa would be replaced by Rosewin Wandi, without giving further details.
Mr Kayukwa is considered to be a close aide to former President Rupiah Banda, who lost last month's tightly-contested elections to Mr Sata.
During the campaign, Mr Sata pledged to stem out corruption among government officials.
And during the swearing-in ceremony last week he said: "Corruption has been a scourge in this country and there is a wide link between corruption and poverty."
The previous government was criticised for not being tough on tackling graft.
