Leah is told: You’re hired! by Lord Sugar on The Apprentice

Leah, who works in London, was named winner of the ninth series of the BBC1 show and bagged £250,000 to plump up her business finances.

She now plans to come home to celebrate her victory with her family.

Ten members of the family, including mum Lorraine and dad, Trevor, were in London as the final programme was recorded.

Totton triumphed over cake shop boss and pal Luisa Zissman to secure Lord Sugar as her new business partner.

Despite Sugar’s earlier worries about the ethics of her business NIKS Medical, Totton managed to reduce his frown lines by ironing out the wrinkles in how her plan would work.

The finalists brought back previous candidates to help them in branding and marketing their business plans before presenting them to a room of industry experts. But series tough cookie Zissman broke down in tears after feeling she’d bungled part of her pitch and her baking supplies online wholesale business, Baker’s Toolkit, failed to rise to success in the boardroom.

Sugar’s new business partner Totton was seen bossing her team around much more than usual in the final task.

She said her family couldn’t believe it “but I’m hoping I keep that assertiveness. (Luisa) took some of the softer side of me and I took some of her bossiness”.

Totton, 25, plans to offer anti-ageing skin treatments at a chain of clinics where she hopes to raise the standards of the beauty industry with her medical credentials. The brand name has changed to Dr Leah at Lord Sugar’s request and Totton is continuing with a masters degree as well as planning to keep her hand in clinical work as a locum.

She said she did not expect her new business partner to become a client any time soon: “I think Lord Sugar’s face is fine as it is.”

The winner also remained tight-lipped about whether her fellow contestants had booked in for treatments, saying: “That’s confidential, I can’t tell you what inquiries I’ve had.”

Despite worries about her entering the tough process, the doctor said her family were “delighted” at her win: “I’m the first person in my family to have even gone to university so it’s such a massive achievement for the whole family.”

Ahead of last night’s screening, Totton said of her plans to celebrate: “I’m not really a big partier. My colleagues are coming round tonight, I’m going to cook and we’ll watch the show together. I’m going to go back to Ireland and be around my family.”

But would she do it all again?

Leah 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, was up against her pal Luisa Zissman to land the prize of a £250,000 investment from programme boss Lord Sugar.

She said the show had been “worth it” for her personally because she had made it to the final – “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 she stressed she had not had any work done on herself.

“I can 100 per cent 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.”
