UK Parliament does not get a binding vote on going to war. Their recourse, if they disagree, is to remove the PM altogether.
Admittedly, I'm not sure there's much of a meaningful difference between the two. If an MP doesn't want to go to war, I'd think that a big enough difference if opinion to vote no-confidence. As such if a majority of Parliament didn't want to go to war, they may have taken that step.
