Prominent British Labor member of parliament Jeremy Corbyn has condemned the execution of protestors in Iran saying that it is “deplorable”.

In a tweet on Tuesday, Corbyn said he has written a letter to Iran’s Chief Justice Gholamhossein Mohseni Ejei urging him to reverse the convictions.

“I have been informed that at least 26 people are at risk of being executed…Many of the individuals involved have been denied fair trials, including the right: to access a legal counsel of their choosing; to be presumed innocent until proven guilty; to remain silent; and to receive a fair, public hearing,” reads the letter Corbyn published on twitter.

He also noted that there are reports that several defendants were tortured to induce “confessions”, which were later used as evidence in court.

Corbyn urged the regime to immediately reverse all convictions and death sentences of protesters and release those who have been detained for exercising their rights to freedom of expression, association, and peaceful assembly.

Holding fair trials, having access to legal counsel, and throwing out evidence acquired through use of forced confession were among the other things Corbyn urged the Islamic regime to do.

Iran has been the scene of nationwide anti-regime protests since mi-September. Over 500 people have been killed by security forces and more than 18,000 are imprisoned.
