A boy from Stockport with a rare genetic disorder has undergone experimental brain surgery in Poland.
12-year-old Marcus Allen has a condition called AADC, which affects how his nervous system works, meaning he can't walk or talk, it is similar to Parkinson's disease.
His family have had to raise £70,000 to get him the treatment, as the surgery is not available, or even licensed in the UK.
Last month we followed the story of Hallie Campbell, from Wigan, who also has AADC.
She also travelled to Poland to have the surgery.
Hallie and Marcus are just two of six children in the country who have the rare condition and they are only two of ten to have had their experimental operation.
