LORD Sugar’s search for an apprentice reaches its penultimate episode tonight with the annual favourite task for the five remaining candidates - several gruelling interviews.

There is nowhere to hide as they are grilled by four of Lord Sugar’s trusted business colleagues, one of whom, Margaret Mountford, returns to the show after years as a team observer.

After they have made their assessments, Lord Sugar’s four advisors give him their opinions and explain their verdicts to him in the boardroom.

As each of the candidates takes their turn to plead their case, three are fired as Lord Sugar delivers his final ruling on who will make it through to the last task.

The two-hour final of the show will be shown on BBC One on Sunday at 9pm.
