The installation ceremony marked the formal commencement of his tenure as the supreme head of the federation, which also reflects the stature of constitutional monarchy practised in the country.
Sultan Muhammad V, 47, previously took his oath of office on Dec 13. He succeeded Sultan Abdul Halim Mu’adzam Shah of Kedah, whose term ended on Dec 12.
Malaysia is one of 43 countries in the world that practise constitutional monarchy, with the rotation system in selection being the only one of its kind.
Some 800 guests witnessed the ceremony, including the Malay rulers and their consorts; the representatives of the Malay rulers; the Yang Di-Pertuas Negeri; Prime Minister Najib Razak and his wife, Rosmah Mansor; and Deputy Prime Minister Ahmad Zahid Hamidi and his wife, Hamidah Khamis.
Also present were cabinet ministers, heads of government departments and foreign diplomats.
The prime minister, representing the government and the people, congratulated His Majesty and pledged loyalty to the newly-installed Agong.
His Majesty then delivered his royal address before the recital of prayers by Istana Negara religious officer Abd Aziz Che Yacob.
Sultan Muhammad V was elected the 15th Yang di-Pertuan Agong at the 243rd (Special) Meeting of the Conference of Rulers at Istana Negara on Oct 14 last year.
