Former News International chairman James Murdoch is to give evidence under oath at Britain's media ethics inquiry.
Murdoch will appear before the Leveson inquiry on Tuesday to answer questions about how much he knew about about phone hacking at the News of the World tabloid.
Revelations that reporters at News of the World had hacked into the phone of a teenage murder victim led James Murdoch's father Rupert to close the 168-year-old newspaper and triggered three police investigations and a judge-led inquiry into media practices.
Murdoch stepped down as chairman of News International in February.
Rupert Murdoch, who is still chairman and chief executive of News International's parent company News Corp., will appear before the inquiry Wednesday. - Sapa-AP
