Indonesia's Pertamina has removed its CEO Dwi Soetjipto and Deputy CEO Ahmad Bambang, company and government officials said on Friday, and has appointed Yenni Andayani as acting CEO.

"The minister and board of commissioners have been watching the issue of leadership at Pertamina," Gatot Trihargo, deputy minister for state-owned enterprises, told reporters.

"We felt that internally we needed to continue to make improvements, so there needed to be a refreshment," Gatot said.
