Professor Imelda Maher:

We need an umbrella and then we can work within it. In terms of the narrative around what is going on, once we get phase one out it will be possible because Brexit means Brexit and we have to say that is Brexit. Then we need to take the really boring technical questions around what the trade agreement is about into the technocratic arena and depoliticise it. There will be points of tension, but that will be the way to allow it. It will then unravel over time.
