Over the course of 12 tough tasks, the 16 candidates will be whittled down until just one victor remains. And plenty of sparks are set to fly in the boardroom along the way!

Each week the budding entrepreneurs will be divided into two teams - led by designated Project Managers - that lock horns under the watchful eyes of Lord Sugar's advisor Baroness Karren Brady and new aide Claude Littner.

After completing each task both teams return to the boardroom to discuss their inspirational or calamitous experiences and discover which side has triumphed.

The winners will be rewarded with a luscious treat while the losing team’s Project Manager must select two colleagues to accompany them back into the boardroom. Lord Sugar will then hear their arguments and fire at least one of them from the competition.

The eventual winner of The Apprentice Series 15 will be given the opportunity to be Lord Sugar's business partner and receive an investment to the value of £250,000 founded on the basis of their idea.
