A video of Prime Minister Najib Abdul Razak showing off his dancing skills at his daughter Nooryana Najwa's wedding do in Kazakhstan has set off a buzz on social media.

However, for conservatives back home in Malaysia where religious authorities impose strict controls on entertainment activities for Muslims, Najib and his wife Rosmah Mansor gyrating to the tune of "Pretty Woman" may not receive a stamp of approval.

Nevertheless, the prime minister's special officer, Rizal Mansor, insisted there was no wrong in it, particularly as Najib and his wife were caught by surprise.
