Police in Zambia have summoned two journalists from a privately owned TV station for questioning over a reportedly leaked budget speech presented to parliament last month.
Diamond Television said its chief executive, Costa Mwansa, and head of news, George Chomba, have been asked to appear before police today.
The authorities want to know how they accessed the speech hours before it was read in parliament by the finance minister.
