It is incumbent on Invest and the Department to identify areas of priority, particularly clusters. The Member is quite right: there is a growing cluster with some big players, but a lot of small and medium enterprises are involved in advancing the sector. Aerospace touches on the areas of good jobs and productivity, in that there is a lot of innovation and growth in the sector, and it is in line with the priorities that I have set in the Department. Also, with quite a lot of the firms scattered across the North, it offers regional balance. We all operate within a limited budgetary framework, including Invest NI, but we have tried to identify sectors with opportunities for growth. I concur with the Member's view that there are clear opportunities for growth in the sector.
