South Africa's police force has an image problem.

Faced with one of the world's highest crime rates, its officers are seen by many as ineffective, sometimes corrupt and often lumberingly overweight.

That's now all supposed to change under Bheki Cele the new police commissioner.

Launching a new zero tolerance approach to podgy policemen, Commissioner Cele completed a round of aerobics and ran 4000 metres round the track.

Over a healthy breakfast he said that officers would from now on have to fit into the size of trousers they wore when they were first trained.

Those requesting an extra few centimetres round the waist will now be politely refused and given a year in which to follow a designated weight loss plan and squeeze into their old size.

Those who still burst the seams will be shown the door.

With the World Cup starting in less than three months time, this is the South African police trying to show that they are up the task of protecting the up to 400,000 visiting fans.
