Umno must be ready for the day when its political rival Pakatan Rakyat no longer has any "dinosaurs" in its midst, Kedah Menteri Besar Mukhriz Mahathir has warned party members.

Referring to seasoned politicians still active in the opposition coalition, Mukhriz said this in justifying why new blood must be elected in the coming party election, in line with his slogan "Berani Ubah" (Dare to Change), which he used when contesting for the Umno Youth chief post in 2008.
