Serbia's tennis star Novak Djokovic is supporting a bid by his father to topple the country's tennis leadership.
Djokovic says the situation's almost out of control and changes are inevitable, but he insists his father isn't interested in any position within the Federation.
Djokovic senior and the Federation president Slobodan Zivojinovic clashed after Serbia won their first Davis Cup title earlier this month with a 3-2 win over France in Belgrade.
Zivojinovic, a dual Wimbledon semi-finalist, is standing for re-election for another four years.
