During the Hari Raya open house hosted by Umno in Kuala Lumpur on Sunday, Prime Minister Datuk Seri Najib Tun Razak told reporters that many people are still asking the questions whether former prime minister Tun Dr Mahathir Mohamad is still standing by his accusations against Datuk Seri Anwar Ibrahim whom he sacked in 1998. Mahathir left Umno in 2016 and now works together with Anwar's PKR party to unseat Najib.
