A Kazakh artist who was born without arms says he could not get permission to enter the UK last month because he could not give fingerprints.
Karipbek Kuyukov planned to attend an anti-nuclear conference in Edinburgh.
But he got a letter from the British Consulate in Istanbul saying his “biometrics were of poor quality” and asking him to resubmit his application.
Mr Kuyukov was born in the region of Semipalatinsk, the former Soviet Union’s main nuclear testing ground.
Many thousands of children were born with disabilities during the nuclear test programme.
Mr Kuyukov has used his painting to campaign for nuclear disarmament for the past 20 years.
