Well, the hon. Gentleman is wasted in this House; he should be in the City, buying and selling futures in oil price shares. I think that is the best way for him to go. The three points that fall from the OBR report are the unpredictability of the oil price, the difficulty of extraction in the North sea and the fact that, whatever way we look at it, oil revenues will be declining sharply over the next 20-year period. It would appear that the hon. Gentleman—[Interruption.] I am happy to take other interventions, but it is quite clear that SNP Members cannot defend their policy for full fiscal autonomy. Indeed, they should listen to their hon. Friend, the hon. Member for East Lothian (George Kerevan), who said that it would be economic suicide. He is an experienced journalist and economist, so they would do well to listen to him.
In conclusion, we will push amendment 38 to the vote because we feel that the permanency of the Scottish Parliament should have the underpinning of the Scottish people by any means that would be appropriate, including a referendum. We will push to a vote new clause 2, which proposes a constitutional convention to resolve some of the larger issues on a constitutional settlement across the country. We will oppose full fiscal autonomy in all its forms, because it would be bad for the Scottish people, bad for the Scottish economy and bad for the future of Scotland.
