Thank you for the question.
I can't speak to how the United Kingdom prioritized its negotiating agenda. It could be the case that they wanted to close some deals which from their perspective were easier than others.
The CETA is a complex and very comprehensive agreement; it takes time to negotiate. I think they were taking some time to develop expertise along the way and then to get the resources in place to do it.
Again, from their perspective they were looking, I think, at.... Their number one market is with the EU, and I think that's where they devoted most of their resources.
