What difference does the person at the top make to everyone else? Does it matter what sort of leader he or she is?

And just what is a good leader? Someone inspirational? Someone confident enough to make bold decisions? Is it someone who cracks the whip, or someone who works as part of a team? Can the same person do both?

Some might argue that a future leader was born that way and showed early signs of their talent. Gordon Brown was famously fast-tracked to university at just 16, and later was the second student to be elected Rector of Edinburgh University - a post which had often gone to a celebrity who rarely visited.

Others, though, would say that a leader can be made; that with the right training and nurturing most of us could inspire others to follow our lead.

On the eve of a change at the top, Wales@Work looks at the question of leadership and its role in the modern workplace.
