I agree that if the benefits of a reduced corporation tax rate for Northern Ireland are to be realised, that needs to be accompanied by a determined effort to sell the benefits of Northern Ireland to the world. I am absolutely 100% certain that if my right hon. Friend the Member for Witney (Mr Cameron) is Prime Minister in the next Parliament, that is exactly what the UK Government will be doing, because he is completely committed to Northern Ireland and believes that it is a wonderful place. That is why he takes every opportunity to tell the rest of the world what a fabulous place it is, and why he brought the G8 summit to County Fermanagh.
Turning to the mechanics of passing the Bill, any delay would be a great mistake. I therefore very much welcome the support that the Bill has received from hon. Members from Northern Ireland, who have rightly highlighted the importance of corporation tax devolution to their constituents and the potential benefits it could deliver. I welcome, too, the recent U-turn by the Leader of the Opposition, who last week confirmed that Labour will facilitate the passage of the Bill. I am most grateful for that. That recognises the firm and consistent support for the change from the five parties in the Northern Ireland Executive, as well as the fact that this new piece of devolution has a key part to play in the Stormont House agreement.
