Gerakan Harapan Baru (GHB) has blasted Prime Minister Najib Abdul Razak for saying that Malays would be "bastardised" if Umno were to lose power.

Najib, who is also Umno president, made the statement during the Perlis delegates meeting in Kangar yesterday morning.

GHB pro-tem committee chief Mohamad Sabu, better known as Mat Sabu, said if Umno were to lose power, Najib would probably be afraid of ending up at the Sungai Buloh Prison in Selangor.
