Mr Kennedy faces a fresh test today when he addresses the Liberal Democrats' Scottish conference in Dundee. Yesterday, in a series of interviews, he again denied as "utter rubbish" the suggestion that he was suffering a drink problem and blamed a severe stomach bug for having missed the Budget. However, he conceded: "Obviously, I had a health setback last week of a fairly severe kind, for which I had to take myself off to bed for several days, and that is not something I want to see repeated."
