Phnom Penh (FN), Feb. 24 – Cambodian prime minister Hun Sen wondered why the opposition always calls him stupid, but has never defeated him.

The premier spoke at the graduation of more than 7,000 RUPP students, held on Friday (Feb. 24) at Diamond Island.

The premier said, "I have received honorary doctorate degrees from many universities in Cambodia and abroad. Yet, the opposition still call me stupid. I wonder if you can not defeat a person who you call [stupid], then who are you?” the premier taunted the opposition group.

Premier Hun Sen also mentioned that the opposition group received education in Cambodia, yet they continue to attack the kingdom’s quality of education.
