Former Perak Menteri Besar Nizar Jamaluddin is standing by his statement that the Kuala Kangsar by-election is to teach Prime Minister Najib Abdul Razak and Deputy Prime Minister Ahmad Zahid a lesson for their role in the 2009 Perak crisis.

This is how he sees the connection between the Perak crisis of 2009 that saw the fall of the Pakatan Rakyat state government and the by-election today, coincidentally both in Kuala Kangsar, he said.
