Defence lawyer Ram Karpal resumed his examination-in-chief of Australian DNA specialist Dr Brian McDonald in Anwar Ibrahim's sodomy trial today.

The hearing continues today after the Hari Raya break, with Anwar potentially facing another scandal, with an Umno-friendly blogger threatening to release allegedly another sex video, dated Jan 12 this year.

Blogger Papa Gomo has also revealed CCTV footage, allegedly taken minutes before the much publicised Feb 22 sex video, for which the infamous 'Datuk T' trio were charged and fined.

Lead defence counsel Karpal Singh had in the past sought the court to take action against individuals who seemed bent on interfering with the administration of justice in this controversial trial.

McDonald, who is the fourth defence witness, is expected to take another two days to complete his testimony, with cross-examination by the prosecution pending.

It remains to be seen whether Prime Minister Najib Abdul Razak and his wife Rosmah Mansor will take the stand this week.
