Parti Amanah Negara says it is worried that the Sarawak state government's act of sending lawyers to London to study the Malaysia Agreement 1963 (MA63) would be inviting foreigners to "intervene" in national affairs.

"If this had been initiated by the opposition, the government would have slammed us ... but this was initiated by the state government itself," Amanah deputy president Salahuddin Ayub said.

Last Friday, Sarawak Chief Minister Abang Johari Openg announced that the state will send a team of lawyers to London to search for and study any references related to the state’s rights under the MA63.

This is an effort to strengthen the state's autonomy, a movement initiated by Abang Johari's late predecessor Adenan Satem.
