Johor Menteri Besar Khaled Nordin must explain the claims of logging, allegedly involving the royalty, being carried out in the state, Amanah deputy president Salahuddin Ayub said.

He made the call after Pelindung Khazanah Alam Sekitar Malaysia (Peka) president Shariffa Sabrina Syed Akil was arrested last week for insulting the Johor sultan by posting on Facebook about logging on land belonging to the monarch.
