Can I thank Jack Sargeant for that? In the comparatively short time that he has been a Member of the Assembly, he has already been clearly identified as a major spokesperson for the aerospace industry, because of its importance to his own constituency. Llywydd, there are some serious analyses that suggest that the aerospace industry in Wales is the most exposed of all to a tariff-infested Brexit. That's not surprising, is it, because the aerospace industry relies on components passing across borders every single day in order to succeed. So, Jack Sargeant is absolutely right to point to the dangers posed to industries and jobs in his parts of Wales if we don't manage to negotiate a sensible Brexit that puts jobs and our economy at the forefront of those negotiations.
