Former premier Najib Abdul Razak continues to live up to his newly earned reputation as the "King of Trolls" with his latest Facebook post on his visit to Langkawi, the constituency of Prime Minister Dr Mahathir Mohamad.

In his posting, Najib sarcastically questioned which government department he had to obtain permission from before being allowed to take selfies with his supporters.

"Yesterday I was looking for apam balik at the Kuah night market.

"Who knows which counter at which department I can apply for a selfie permit?" he asked.

Najib's post was accompanied by two photographs believed to be taken during his visit to the night market in the Langkawi town.

It is also believed to be in response to several local Bersatu leaders lodging five police reports ahead of his visit. 

Yesterday, Deputy Communications and Multimedia Minister Eddin Syazlee Shith, also a Bersatu leader, said the police reports were lodged to safeguard public safety on the island.

Negeri Sembilan Bersatu chief Rais Yatim, however, said there was no need for such reports, as Najib was only visiting Langkawi to be with his supporters.

The former premier had earned the "King of Trolls" moniker following a series of viral Facebook postings attacking Harapan leaders and various government policies.
