Based on public sentiments, PAS president Abdul Hadi Awang believes the nation is ailing from a serious ailment and urged Prime Minister Dr Mahathir Mohamad to conduct a major operation.<br /><br />He was commenting on the premier stating he is considering reshuffling the cabinet following Pakatan Harapan's crushing defeat in last Saturday's Tanjung Piai by-election in Johor.<br /><br />“He (Mahathir) is a doctor right. If it is a human, he knows which part to operate on.<br /><br />“This is like a disease and if we don't treat it, it will spread... He (Mahathir) is a veteran politician since the time of Tunku Abdul Rahman and Tun Abdul Razak.<br /><br />“So he knows which part to cut, operate or stitch,” he was quoted as saying by Sinar Harian in Rusila, Terengganu, this afternoon
