Former prime minister and Pakatan Harapan chairperson Dr Mahathir Mohamad took his ceramah campaign against the BN government to Kamunting, Perak last night.

Accompanying him were top Harapan leaders and activists, who peppered their speeches with jokes about the now defunct Internal Security Act 1960 (ISA).

Kamunting, a town north of Taiping, is best known for its detention centre for offenders of the ISA, which allowed for detention without trial.
