Former prime minister Dr Mahathir Mohamad has filed an application for a mareva injunction against Najib Abdul Razak to freeze or prevent the prime minister from transferring, reducing (withdrawing) or dealing with assets worth RM2.642 billion.

Mahathir, 91, along with former Batu Kawan Umno vice-head Khairuddin Abu Hassan and former Langkawi Umno member Anina Saadudin, also filed an application for discovery, requiring Najib to inform and itemise his assets, including properties, credit balance, money and other assets kept in banks, financial institutions and as company shares.
