A young girl in desperate need of a lung transplant has moved her doctor to tears after writing him a letter thanking him for his help and being her "star".
Last Christmas Elle Grace Morris - who suffers from cystic fibrosis - was told that she might not live for another year, but thanks to her dedicated medical team she is able to thank them for their help this Christmas.
"Without your help I don't know if I'd be here today, thank you" the 10-year-old wrote in her card to Dr Ravi Jayaram, a consultant paediatrician at the Countess of Chester Hospital.
After wiping away his tears, Dr Jayaram - who has been treating Elle since she was diagnosed at 15 months old - promises to "write to Santa for those new lungs for you".
Elle's mother, Becky Whitfield, also praised Dr Jayaram: "Dr Ravi is amazing. His comical character always keeps Elle's spirits up.
"He goes beyond his duties as Elle's consultant to make sure she is comfortable and as healthy as she can be when having her treatments and medication.
"He is a huge credit to the NHS."
Yet Dr Jayaram was full of praise for Elle who he described as "one of the toughest, bravest and most positive little girls I know".
When Elle, from Nantwich, Chester, learnt that she needed to go on the transplant list, she wrote a list of 10 things she wanted to do before she reached the age of 10.
Currently Elle's lungs are only functioning at 30% and she must take an oxygen tank with her everywhere she goes.
Yet according to Ms Whitfield, doctors at Great Ormond Street Hospital - where it is hoped her lung transplant will take place - said they cannot believe how much Elle pushes herself, and had expected her to be in a wheelchair and not attending school full-time.
She has already achieved many of her wishes, including meeting singers Rita Ora and Olly Murs, as well as making her own music video and being a princess for the day.
Another of her wishes was to raise awareness of the Cystic Fibrosis Trust, something she has now achieved with the release of their newest video.
Cystic fibrosis is a life-shortening genetic condition that causes the lungs to become clogged with mucus, making it hard to breathe. Half of those who die from cystic fibrosis are aged 28 or younger.
Anyone who wishes to donate to the CF Trust should text ELLE to 70500 to donate £5.
