Jason Gillespie says the Pakistan Cricket Board's failure to consult him on key decisions was the reason for his resignation as the country's Test coach.

Former Australia bowler Gillespie took over as Pakistan's red-ball coach in April, only to step down after just eight months in the role.

His exit followed that of white-ball coach Gary Kirsten, who began his role at the same time as Gillespie but quit in October.

Gillespie lost his first series in charge against Bangladesh and was removed from Pakistan's selection panel when they opened their recent series against England with a defeat.

However, they recovered to triumph 2-1 with wins in Multan and Rawalpindi.

Speaking to ABC Sport, Gillespie said the PCB's choice to fire coach Tim Nielsen, in addition to other incidents, led him to reconsider his future.

"I was completely and utterly blindsided by a decision to not have a high-performance coach," Gillespie said.

"I just thought after a number of other things that had gone on in the previous few months, that was probably the moment where I thought, 'Well, I'm not really sure if they actually really want me to do this job or not.'"
