JOHOR BARU: Former prime minister Datuk Seri Najib Tun Razak has criticised Johor Mentri Besar Datuk Osman Sapian for leaving the state to attend a working trip to Batam, Indonesia despite the chemical dumping incident in Pasir Gudang.
Najib pointed out that Osman should not have gone overseas as the toxic dumping incident along Sungai Kim Kim was a very serious matter.
