DAP veteran Lim Kit Siang has urged former prime minister Najib Abdul Razak to take "roti canai" roads into the interior of Cameron Highlands, to see how he has failed the local Orang Asli community.

"As he will be here for four days from Thursday to Sunday, I hope he will travel the worst 'roti canai' roads and non-roads to the remote Orang Asli kampungs to see for himself how as the sixth prime minister, he has failed the Orang Asli in Camerons Highland and the country to provide the most basic of infrastructure," Lim said.

He said the terrible conditions of the roads had to be seen to be believed.
