Selangor Menteri Besar Azmin Ali has been advised by a Selangor Umno leader not to speak about economic matters, lest he displays his alleged ineptitude in the subject.

“Mathematicians should stay quiet and do their sums, don’t talk about the economy if you lack the expertise.

“We are not talking about the value of RM600 to the individual, but on the total impact of the injection of RM5 billion into the market,” Selangor Umno vice-information chief Mat Nadzari Ahmad Dahlan was quoted as saying by the BN Backbencher's Club portal.
