ISLAMABAD — Transparency International Pakistan has urged the International Cricket Council to investigate what it calls the “unconstitutional” appointment of Najam Sethi as acting chairman of the Pakistan Cricket Board. TIP wrote to ICC President Alan Isaac Wednesday, saying “in our opinion Sethi's appointment is unconstitutional.” TIP also asked the ICC to “adhere to its own principles to ensure corruption-free cricket in the world and especially to observe that national boards follow their own constitution duly approved by the ICC.” TIP's letter to the ICC comes just two days before Sethi is scheduled to attend the ICC board meeting in London. — AP
