The Apprentice 2013 final: Leah Totton 'couldn't do the show again'

Leah does battle with Luisa Zissman in the show's final tonight

Finalist Leah Totton says she would not have entered The Apprentice if she had known how tough it would be.

The qualified doctor, a cosmetic enhancement expert from Londonderry, is up against her pal Luisa Zissman to land the prize of a £250,000 investment from programme boss Lord Sugar.

But she said: “I think it's been worth it for me because I've got to the final and have a chance of winning it - but I don't know if I could put myself through it again, I found it really hard.”

Totton, who now lives in London, worked on a business plan to open a chain of cosmetic procedure clinics for her final project on the show. But stressed she had not had any work done on herself.

“I can 100% verify I have not had any treatments done,” she said. “I don't have wrinkles, I'm only 25 and they're not treatments that are aimed at my age group.

“They're anti-ageing treatments and at 25, certainly no - I have not had any. And I'm certainly not looking to have any in the near future.”

She also said she didn't expect craggy-faced show boss Lord Sugar to become a client for an overhaul any time soon.

He famously had some work done on the bags under his eyes, but she said: “I think Lord Sugar's face is fine as it is.”
