Indian Olympic Association (IOA) President PT Usha on Monday said that the revolting Executive Council members were trying to sideline her by their acts of defiance, including issuing termination letters to an official appointed by her. On Friday, nine EC members had pasted a signed notice at the IOA office premises here, asking "unauthorised persons" not to enter its headquarters. The notice, which Usha termed as "arbitrary", was directed at two recently appointed officials. A majority of EC members had earlier claimed that they had signed a suspension order declaring Raghuram Iyer's appointment as IOA CEO in January as null and void.
