Two judges have been sacked from the panel that picks the Nobel prize for medicine in a scandal surrounding a disgraced Italian transplant surgeon, reports BBC.

The decision to fire Harriet Wallberg and Anders Hamsten came after the Swedish government sacked the entire board of the prestigious Karolinska Institute, where the scientist worked.

Paolo Macchiarini was seen as a leading specialist on windpipe transplants. But two of his patients died and he was accused of falsifying his work record. Dr Macchiarini denies all the charges against him.

The two judges who lost their positions on the Nobel panel have both served as heads of the Karolinska Institute, and were among several individuals suspected of ignoring warnings about the Italian windpipe scientist. The 50-member Nobel panel is due to announce the winner of the annual prize next month.

"Scandal is the right word," higher education minister Helene Hellmark Knutsson said on Monday.

"People have been harmed because of the actions of the Karolinska Institute and also the Karolinska University Hospital."

Paolo Macchiarini was hired in 2010, two years after he was part of a team that carried out the first windpipe transplant partly made of the patient's stem cells. In 2011 he was hailed for leading a team that carried out the first synthetic organ transplant.

But he lost his job earlier this year after a TV documentary by Swedish broadcaster SVT showed footage of operations he carried out in Russia which the Karolinska Institute itself described as "truly alarming".

Prosecutors in Sweden said in June they were investigating the stem cell surgeon on suspicion of two cases of involuntary manslaughter at Swedish hospitals in 2011 and 2012.

Other reports have alleged that he gave false information on his resume.
