I would hope the Iraqi Parliament would take notice of the highly paid Prime Minister Maliki and evaluate his performance since he has been on the job to warrant such a high salary. To be paid the most in the world of any government leader is a statement in itself.
If PM Maliki deserves it than let him keep it but I think Parliamentary members are thinking twice about their own salaries the next time they are up for re-election. I see pay raises from PM Maliki to the Iraq Parliamentary to keep the good times rolling!!
