I thank the Member for giving way. When Invest goes out across the world to sell Northern Ireland, a big issue is ensuring that it has a suite of products for potential customers. Corporation tax will play an important role in that. Some of the comments made by some of the Member's colleagues on the issue raise a concern about their commitment. Given the issues that he rightly raises about the sites in Ballymena, does the Member agree that part of the overall suite in selling is the date and the rate that we have now secured for corporation tax? When we visit the United States in March, every effort must be made to ensure that that is a key component of the sell for Northern Ireland.
