Who is head of state?

This column is a Citizen Ranger report and not part of my series on 1Bangsa Malaysia.

A good friend from Singapore was upset that PM Najib Abdul Razak did not attend the state funeral for the late Singapore leader, Lee Kuan Yew. I then did some research and found out that the Yang di-Pertuan Agong attended; and he is our head of state. I suppose the PM could have attended, but the government wanted the highest and most symbolic form of representation for Malaysia.
