Ahmad Zahid Hamidi has a knack for stealing the thunder. But it is often followed by bolts of criticism such as in the case of his infamous 'Chinese who vote DAP are ingrates' remark.

Based on this symptom, Lim Kit Siang diagnosed the home minister with an illness he said was spread by former premier Dr Mahathir Mohamad. It is called "Mahathirish perverse illogic".

The DAP veteran also criticised Zahid for "casting a long shadow" on the 40th anniversary celebrations on the establishment of diplomatic ties between China and Malaysia.
