The absence of EFCC witness, Mr Micheal Wetkas, on Wednesday stalled the trial of Senate President Bukola Saraki at the Code of Conduct Tribunal (CCT).
Saraki is standing trial on allegations bordering on false assets declaration and money laundering.
He had earlier pleaded not guilty to the charges.
At the resumed hearing in Abuja, for the continuation of cross examination of Wetkas, EFCC lead prosecution counsel, Mr Rotimi Jacobs (SAN), sent a letter to the tribunal seeking adjournment.
Jacobs is seeking adjournment on the grounds that Wetkas is giving evidence in another criminal case involving former Governor of Jigawa, Sule Lamido and his son, Aminu, in the Federal High Court, Abuja.
The prosecution counsel urged the tribunal to adjourn the case till either June 9 or June 10 for continuation of hearing.
No new date has been fixed for continuation of hearing.
