This is the heart-warming moment a pensioner personally thanked the mum who saved his life with her anonymousstem cell donation- after a 2,300-mile journey.

Jackie Wray, 50, met with her genetic twin, Siegfried Siggi Wahl, 71, in September after the pair spent more than three years communicating anonymously due to the laws surrounding stem cell donations.

Siggi, from Hattersheim in Germany, was diagnosed with chronic myeloid leukaemia in April 2015 after he had suffered a stroke and doctors found the cancer when he was hospitalised.

After initial treatment proved unsuccessful, doctors told Siggi that his best chance of survival was a blood stem cell donation from a person with identical tissue type.

Unfortunately nobody in his immediate family proved to be a match, so he then had to turn to the worldwide register to find a stranger willing to help.

Luckily, just six months earlier, Siggis genetic twin Jackie, from, had signed up with blood cancer charity DKMS in 2015 after seeing a TV appeal for a child in urgent need of a donor.

Moving video captures the moment Siggi met his angel Jackie at her restaurant and bar in Great Ayton, North Yorkshire for the first time earlier this year.

Jackie said: Before we met, I had no idea what Siggi looked like or how old he was it was very difficult when we could only write to each other and I burst into tears every time I read his cards.

When he arrived, there were lots of tears and lots of cuddling Siggi and his wife had made me a photo album with pictures of him during his treatment which just made me cry instantly.

They also bought me a little angel necklace because they say Im his angel and it was just so lovely, I will treasure it forever.

Dad-of-two Siggi added: After the many cards we exchanged anonymously, I felt that Jackie has a heart.

She wanted to save people's lives, and such a person deserves a personal thank you, with a big hug, and of course with a lot of tears.

Neither of us could let go when we hugged - for me, she is my angel that saved my life.

Mum-of-two Jackie is planning her second meeting with Siggi in Germany for his birthday in January (Caters)

Jackie is now calling for others to sign up to become a donor with DKMS to help change peoples lives.

The mum-of-two is planning her second meeting with Siggi in Germany for his birthday in January and is looking forward to meeting the rest of his family.

UK law states that whilst donors and their patients can communicate following the transplant, it must remain anonymous for at least the first two years.

After this, if both parties are in agreement, their identities can be revealed and they can make arrangements to meet.
