Charles Kennedy has admitted he has an alcohol problem. Albeit after he was told it would be exposed to the voters. It was covered up for long enough by his party. Should his colleagues show unconditional loyalty to their impaired leader or to the voters they hope to win over?

In the interests of his party he should have resigned before being issued an ultimatum. Lots of people drink without it becoming a 'problem'. But once it does become such, then the person with the problem should be seeking professional help not votes.

Over eating to the point of obesity is another kind of illness. I can see the similarity in such that it shows a person with lack of self control. And it could conflict with the party image to promote health . But obesity is a visible illness and the voters can judge for themselves as to whether they wish that particular person to represent them. It doesn't necessarily have an adverse effect on their decision making skills.

Kennedy's illness was hidden as with most alcoholics until those around him lost confidence in him.
