Former Daily Telegraph owner Conrad Black stepped down as chairman and chief executive of Hollinger Incorporated today.

Former Daily Telegraph boss Conrad Black suffered a legal setback when a US federal judge upheld an agreement designed to prevent any interference with a committee investigating the finances of the company he once headed.

Newspaper baron Conrad Black should have received notice before a court entered an emergency order restricting his authority to replace the board of directors of holding company Hollinger International, a federal judge ruled in Chicago.
