A medical professor has confirmed that Vladimir Putin likely has Parkinson's disease as footage showed his leg uncontrollably shaking.
There have been unconfirmed rumours that the Russian President is unwell, with many people from Kremlin insiders to western physicians giving their thoughts.
Some claim he is fighting a form of cancer, while other experts are convinced the 69-year-old has early-stage Parkinson’s disease.
"All this talk of thyroid cancer... if you had that five years ago, I don't think that would be a problem now," Professor Angus Dalgleish of St George's, University of London, told The Mirror.
However, he continued: "I do think that the one solid piece of evidence we see routinely is the shaking of the hands and I think that that is a degenerative thing like Parkinson's."
Last month, when the Russian brute met with Belarusian President Alexander Lukashenko in Sochi, he was caught on camera awkwardly twisting his feet when the pair sat down for talks.
Then at the weekend, Putin presented the State Prize of the Russian Federation to filmmaker Nikita Mikhalkov at the Kremlin.
He was seen unable to stand still, seeming to sway back and forth as he listened to the recipient accept the prize.
He could be seen shaking his legs as he appeared to make side-to-side movements.
"Tremors would be consistent with Parkinson's and certainly the tremors he has in his hands are all consistent with the disease," Professor Dalgleish said.
He said to confirm cancer we would need to see a scan, but with Parkinson's, there have been numerous videos from different occasions, so we can "definitively go on those movements that we see on videos".
He continued: "You can't say from a short clip like that whether someone has cancer, except there have been several different times and different scenarios where the shake is constant and it gets quite bad.
"So I can assure you that things are rarely straightforward but I would put my money on the fact that he's got about Parkinson's."
The medical professor also said Putin often presents with a "deadpan face" which is "classic Parkinson's".
On parkinsonsdisease.net, they say one symptom is a "mask-like expression, also known as hypomimia." It can cause "trouble producing emotional speech (dysarthria) and problems recognising the emotional, verbal, and nonverbal cues of others".
A Kremlin insider, who claims to have detailed knowledge of Putin’s supposed health issues, claimed Putin also from "Parkinson's disease and schizoaffective disorder".
Publicly the Kremlin has stated that Putin is fit and well but his strict precautions during the pandemic and use of a long table to meet other political leaders have strengthened rumours.
