As my hon. Friend has seen, the outline political declaration makes reference to the free trade area that we will be negotiating with the European Union and, indeed, to the need to ensure that we have those good arrangements across our border. As was outlined in the joint statement that accompanied the outline political declaration, there are two areas, in particular, where further negotiation is continuing. One of them is this issue of the trade relationship. The other is, as I indicated in my response to Yvette Cooper, aspects of the security relationship that we are continuing to negotiate. But we continue to work on the basis that my hon. Friend has set out of the importance of that frictionless trade across borders.
