My hon. Friend is completely right. In fact, it is difficult to expostulate all the different scenarios that may occur in future, so it is best to avoid that, but we know what worked well—the status quo ante the 2011 Act.
As I say, we have experienced the consequences of a statutory scheme and we know what happened in 2019, but the amendment is also dangerously silent on critical questions of implementation and is likely to have undesirable consequences for our constitutional system. For example, it is likely to have negative consequences for the fundamental conventions on confidence. The privilege to request that the sovereign exercise the Dissolution prerogative is an Executive function enjoyed by virtue of the ability of the Government to command the confidence of the Commons. That is the alpha and omega of everything, and should not unduly constrained by any sort of prescriptive parliamentary process that would be disruptive and unhelpful when expediency is essential.
