Week 10 sees the candidates unleashed on the pet industry, creating products, crafting campaigns and pitching for sales. In the boardroom, for at least one candidate, it's walkies.

It's week 7, and the candidates take on TV selling, selecting products which they hope will win over the nation before selling their socks off on a TV shopping channel.

It's week 8, and the candidates are sent to the Isle of Wight to secure nine items for the best price. A last-minute dash to the finish sets up a close race in the boardroom.

It's week 7, and the candidates take on virtual reality fitness. They're tasked with building demos and brands before chasing investment. In the boardroom, for one team, it's game over.

The candidates head to Egypt to put on corporate away days. One team heads to the desert but ends up having a bumpy ride, and the rest run a lagoon tour which is anything but relaxing.

Week 3, and it's chicken v egg. The candidates race to turn ingredients into a profit, but ruffled feathers and picky eaters spark drama in the boardroom.

Once upon a time, 18 candidates were tasked with creating a storybook. Unfinished illustrations and a stinky storyline mean the fairy tale is over, and another candidate is fired.

Lord Sugar's business hopefuls jet off to Hong Kong on a mission to secure nine items at knock-down prices. In the boardroom, the boss is back and the firing finger is fully loaded.
