Word has it he is next to useless on anything technical/operational and will dither and stall till the cows come home finally doing just what his department tells him.
I can confirm MT from personal experience in trying to get Mr McCormack to take action on something involving his portfolio that he IS useless on anything technical/operational, DOES dither/stall, and DOES exactly what his department/minders tell him, which is 5/8ths of the sqrt of FCUK-ALL.
He is a complete and utter waste of time.
Sunfish needs to be listened to!!
