Dr Julian Lewis: Surely specialisms are to be held by the people best qualified to fill the posts, but how can that be reconciled with a situation in which people are confined to applying for posts in certain geographical areas? That means that if there are only two or three posts going in an area, and someone is the third or fourth best qualified person in the area and so does not net the post, they are unable to qualify, or even to apply, for similar posts in other parts of the country, even though they may be much better than the people who are allowed to apply for those posts.
