PKR president Anwar Ibrahim has scheduled a press conference at 12pm today to make "an important announcement".
Speculation is rife that the Port Dickson MP has cobbled together enough MPs to have a majority in Parliament.
Meanwhile, Prime Minister Muhyiddin Yassin is scheduled to make a special address at 2.30pm today.
According to a poster sent out by his office, it will be a "Kita prihatin" (we care) address.
