The Cockar Commission, which is investigating the sale of the Grand Regency Hotel, has another 30 days to complete its work.

President Kibaki extended the commission's mandate for the third time after the expiry of its current one on Tuesday.

On Tuesday, Commission chairman, Justice (rtd) Abdul Majid Cockar had adjourned the sitting early after an application was made for the PS Treasury, Mr Joseph Kinyua to be summoned to give evidence.

Commission secretary Mr Anthony Ombwayo said they will not be calling more witnesses.

Mr Kinyua will first give his statement so that Mr Cockar can make a ruling on whether he will appear before him to give evidence or not.

The ruling will be made on Friday.

The commission's assisting counsel Mr Wilfred Mati had said in his application that Mr Kinyua should testify as Treasury's representative. Former Finance minister Amos Kimunya did not appear before the Commission.

Mr Ombwayo said they expect to record the PS statement in the course of the week.

"On Tuesday the PS was very busy and we could not get him."

He added that the extension will enable them to compile the report and make recommendations.

"Lawyers appearing for various parties will also get time to make their submissions," the commission's secretary added.

At least 21 witnesses have given evidence before the commission, which has been sitting since August 4.
