Novianti Setuningsih – With the trial of former Democratic Party treasurer Muhammad Nazaruddin wrapped up, the Corruption Eradication Commission (KPK) has moved on to investigate some of the graft suspect's claims, starting with the questioning of Atthiyyah Laila, wife of Democratic Party chief Anas Urbaningrum.

KPK investigators will call Atthiyyah in for questioning on Thursday. It is the second summons the KPK issued for Atthiyyah, who said a parent was ill and cancelled last week's appointment.

Atthiyyah served as a board member of Dutasari Citralaras, a subcontractor of Adhi Karya – the construction company at the center of graft allegations surround the construction of a Rp 1.1 trillion ($119.9 million) Hambalang sports center in Bogor.

Nazaruddin also implicated her husband, Democratic Party chairman Anas, in the graft-ridden project, stating that Anas rigged the construction bid for a 10 percent cut from the winning contractor. That money reportedly was used in Anas' campaign in Bandung.

Several others have been questioned in connection to graft allegations, including Munadi Herlambang, the secretary of the sports and youth division of the Democratic Party.
