In the first place who gave her the authority to speak out on the issue? As a political secretary what's her locus standi on palace matters?
It's a great embarrassment for the Selangor government, which has given proof that they have no idea how to run a government.
Arrogance have gotten into their head, so much so, they failed to observe protocol.
What is Khalid Ibrahim doing asking his political secretary to make such ludicrous and absurd statement blaming the palace for not asking to be invited.
Nobody, who has sense of shame, would asked to be invited, even to a friend's party. If you don't get an invite from your friend means you are not liked and the person is not a friend.
It shows Khalid is as dumb, if not dumber, than his political secretary, who has added insult to injury, which may further enrage the Sultan.
The right person who should clear the air and apologise to the Sultan is the STATE SECRETARY and the MENTERI BESAR himself.
Read what the political secretary said of the Sultan here.
Khalid stop making excuses, just go eat humble pie and apologise to the Sultan for the oversight and sack your political secretary immediately or if she received instruction from you, sack yourself.
To err is human, to forgive divine. The Sultan may forgive you for your stupidity.
