The four remaining candidates in The Apprentice 2011 are set to go head to head in Sunday’s final, as they compete to become Lord Sugar’s business partner.

The quartet – Tom Pellereau, Jim Eastwood, Helen Milligan and Susan Ma – are all hoping to win the top prize of £250,000 from the business guru plus his backing to start or expand their own business.

However the final will see them having to survive the job interview from hell as they present their business plans to a number of Lord Sugar’s associates.

They will face interviewers Claude Littner, Mike Soutar, Matthew Riley and Margaret Mountford – formerly one of Lord Sugar’s sidekicks on the show – as their proposals come under the spotlight.

And Lord Sugar said that the process would really highlight who was a worthy winner.

“Once my trusted colleagues get them under the microscope I have no doubt that flaws will be uncovered, and we will see who truly warrants my investment,” he said.

The two-hour special begins on BBC1 at 9pm, including a special edition of You’re Hired, in which Dara O’Briain talks to the winner.
