Prue Leith was left with some conflicting feelings when it came to her adopted daughter Li-Da Kruger finding her birth mother in Cambodia.

The Great British Bake Off judge already shared biological son Daniel with her late husband Rayne Kruger when they adopted their daughter at one-year-old in the 1970s.

Now, the mother and daughter are appearing together in Channel 4 documentary Prue Leith: Journey with My Daughter as Kruger, now in her mid-forties, returns to the country of her birth to explore her heritage.

Within the programme, they find one woman who could potentially be Kruger's mother and while Leith, 80, hoped the pair would be reunited, she also had reservations.

She told The Guardian: “I remember desperately hoping she was Li-Da’s mother, because I knew how important it was for Li-Da to find her.

"Part of me thought, Oh god… she has a whole family. I’ve had Li-Da for 45 years am I prepared for her to focus on the Cambodia side of her family and see much less of her?"

Kruger hails from Phnom Penh, but left the country as a youngster before the Khmer Rouge took hold and millions of Cambodians died under the regime.

The new documentary isn't the first time she's attempted to trace her routes, having done so before at the age of 27.

But while in the process of trying to adopt a two year old boy of her own Kruger was prompted to discover her own history in order to "fill in the gaps" for her son.

Prue Leith: Journey with My Daughter airs Tuesday 14 April at 9pm on Channel 4.
