In the interests of putting the brakes on runaway Parliamentary power, I would think it would be the Queen's duty to the people to stop a bill like this. After what the Commons did to the Lords, somebody has to step up, and what better way than to have the monarch in a constitutional monarchy defend the constitutional part. She wouldn't necessarily be acting politically, she would be preserving the proper process. Maybe you guys need a constitutional crisis, the current situation sounds untenable.

Some day, Labour will not be in charge. It will happen. And when it does, who do you think would be the first to complain about these powers? Being able to quickly force through legislation is a BAD thing, no matter what country or party we are talking about. The harder it is to get a law passed, the better.
