Yes, I'm glad to do so. The good news is that the implementation of phase 1 of the Windsor framework seems to have gone fairly smoothly and I know that that was the hope of officials on all sides. That's in part because of the lead-in time, so there was recognition of the fact that this needs to be done in phases and that there needs to be close engagement with the stakeholders. Now, as we know, phase 1 particularly relates to retailers, most particularly supermarkets, so the most complicated type of movement that you have crossing a border—the thousands of items on a supermarket lorry. So, there was going to be a big challenge there. I think the smoothness of the implementation of phase 1 from 1 October has been in part because you've been able to have direct engagement between UK officials and, indeed, Northern Ireland officials and those directly involved. So, you're really only talking about half a dozen big supermarkets. So, because you've only got that relatively few number of big, big stakeholders here, the engagement has been very direct and quite intense, I think. So, that's been positive.
There have been some occasions where there was concern that information wasn't coming forward that was detailed enough to be of use. And I think, in many cases, the role of the devolved departments was particularly important, so DAERA, the Department of Agriculture, Environment and Rural Affairs, was really key in trying to get information from Whitehall on that and then convey that to businesses here. A lot of it's around interpretation of the rules. So, that came, in some cases, later than I think businesses would've liked, but big problems were avoided. And in other areas, it's partly about expectation management, so businesses being clear as to what would be required from them when, and where paperwork was required that they hadn't expected that could cause some hiccups. But generally speaking, it's been fairly smooth.
I would expect, maybe, to see some more difficulties down the line. So, Christmas time, when you have an increase in the amount of goods crossing the Irish sea, maybe things that wouldn't normally be coming across, that may add to pressure. And also, as you know, this Windsor framework will be rolled out in several phases, and it becomes more complicated, involving many, many more businesses over time, including smaller businesses. And when you're getting to smaller businesses, whether they get the information on time, whether they know where to look, whether they know they need information—all of those things are really important. So, that will be part of the challenge, I think, when we see the second green lane coming into effect in a year from now.
