The journalist who received the sex tape at the centre of trial of US R&B star R Kelly has been ordered to appear in court.

Chicago Sun-Times music critic Jim DeRogatis has been told that he must take to the stand later today (June 4th).

DeRogatis has argued that his rights as a journalist would be violated if he testified.

The journalist was given the tape, which shows explicit sex acts between a man and girl who is believed to be underage, in 2002 and passed it onto local authorities in Chicago.

R Kelly, who faces fourteen charges relating to child pornography offence, denies that he is the man in the video.

If found guilty, the R&B singer could face up to 15 years in prison.

The prosecution rested on Monday (June 2nd) after spending two weeks questioning witnesses in the case. The trial continues.
