Self-evidently, government is a matter of continuity. Issues pass from one parliament to another and from one government to another and it is not unusual to find the sins of one visited on its successor. So it is with Rosyth, the focus for one of the worst of many bad decisions made by the last government. In 1993, for no discernible good reason (although suspicions of plenty of bad ones), the contract for refitting the new Trident submarines was given to the Devonport Dockyard in preference to Rosyth which was well-advanced with preparations to do the work. Public money already spent at Rosyth was

wasted and the many problems of Devonport, mostly known when the contract was awarded, have involved the sinking of more large sums of

public money into the Plymouth yard. As our Defence Correspondent describes this morning, the latest work at Devonport is far behind schedule, and grossly over budget. In this sort of situation, the Labour Government can do no better than be completely honest about the extent of the problem and its possible solution. The public accounts committee will hear evidence of the

situation this week and its members are likely to be shocked. But there is questionable benefit in juggling the operational schedules of submarines in such a way that they will extend their period of service without refit. The danger in that course of action lies in the impossibility of knowing whether the Devonport work will be done in time for the refit, even if it is put back because the first submarine's nuclear reactor is allegedly running so well. The government at least has the luxury of knowing that it did not create the problems, but neither should it compound them. To that end, the consortium which runs Devonport should be told to get back on schedule and absorb all of the extra cost or someone else will be found to run the yard.

Secondly, simple strategic commonsense demands the retention of Rosyth's skills, and the immediate denial of any plans to cancel the refit of S-class nuclear submarines there.
