KUALA LUMPUR: Umno has demanded that Datuk Seri Najib Razak be placed under house arrest immediately and that action be taken against anyone defying the Yang di-Pertuan Agong's order.

Its secretary-general, Datuk Dr Asyraf Wajdi Dusuki, said the party welcomed Sultan Ibrahim, King of Malaysia's decree on implementing the Pardons Board's decision allowing Najib to serve the remainder of his prison sentence under house arrest.

Asyraf said the King's decree made clear that all conditions of the conditional pardon had been fulfilled, including payment of the RM50 million fine.

He said any argument disputing the pardon would therefore amount to defying the King's order.
