Parliamentary accountability—and I say this as somebody who's been in government—means that sometimes you can be heading towards a mistake, and it's Parliament rather than your civil servants or the experts who will tell you that you're heading for a mistake. You'll suddenly find your arguments deteriorating in front of your own eyes when you have to make them in public in Parliament, so it's important in time of crisis to have Parliament even stronger than ever, because the decisions the government is making are so huge.
