The 'historic meeting' between Dr Mahathir Mohamad and his arch-rival Anwar Ibrahim may cause unhappy PKR members to quit the party, Deputy Home Minister Nur Jazlan Mohamed believes.

"Mahathir met Anwar, why? He wants to court the support of PKR. (But) he forgot that many people left Umno to join PKR 20 years ago because of what he did to Anwar," he said.

"So, when he met Anwar to show his support, I think it would turn off many PKR members," Nur Jazlan told a press conference after attending a Home Ministry psychology security seminar in Putrajaya today.
