Former premier Mahathir Mohamad has again dared Malaysian Prime Minister Najib Razak to a public debate, saying the latter should have nothing to fear from a 93-year-old. Najib did not show up the last time he was invited for a debate at the Nothing to Hide forum which also featured Mahathir, last August. Mahathir, was alone on stage to address questions from the audience of about 500 on contentious issues that have been raised about both the Pakatan Harapan chairman and the prime minister. Hundreds of Felda settlers and their families turned up at the closely-watched visit by Mahathir to Pekan in February, the home constituency of Malaysia’s Prime Minister Najib Razak.
