Should the PCB Chairman Have to Sign Off Squad Selections?

[Saj]

I've never quite understood why any PCB chairman has to sign off a squad selection.

Also I'm not aware of this happening in any other cricket board.

With all due respect to Zaka Ashraf, he won't really know the difference between player A and player B, so why have this procedure in place?

Also responsibility of the squad should rest with the selectors and to a certain degree with the coach and captain which is another reason why this procedure of the Chairman signing off and approving any squad is ludicrous.
