Is the Cabinet ever the predominant body in UK politics? I think not. I mean when we look at Iraq, I know of at two least cabinet ministers who did not support the Iraq Qar, Robin Cook and Claire Short, yet what was their fate? Both resigned and the war went ahead as Blair had wished for.So, it shows that at the end of the day, no matter what the ministers think, the PM, who has alot of presidential powers calls the final shots. Just a random point, but thats my take on it, albiet very, very limited.
