Sir Jonathan Stephens:

I think it does a number of important things. First, it fills in what you might think of as a number of loopholes in the original design of the Northern Ireland Act 1998, which simply did not contemplate the sort of situation in which we found ourselves in 2016.

Secondly, and perhaps most importantly, it provides time and space for the Executive or for party leaders to resolve fundamental differences, if and when they arise. As you will know, the previous scheme provided only for periods of either seven or 14 days for the formation of the Executive and the appointment of the First Minister and the Deputy First Minister. We went through those early deadlines very quickly indeed in 2016. We were left in the unprecedented situation of having no means of restoring the Executive without fresh legislation at Westminster.

It is important to say that these changes provide a number of mechanisms that will help in the resolution of fundamental differences, if they arise again. They provide greater assurance for continuity of decision making, but, of course, nothing is perfect. I have always thought that if there is absolute determination to bring about the collapse of the institutions, or such a deep and fundamental breakdown in trust between the parties that they cannot be restored, then no amount of clever constitutional provisions will get over such a fundamental breakdown.
