The left-winger was said to have claimed Mr Henning’s death was “the price of jingoism” when he addressed a Stop the War rally just a day after the video of the killing was published online.
Jeremy Corbyn also added that the rise of ISIS, the terrorist organisation responsible for the bomb attack at Manchester Arena that killed 22 men, women and children last week, was “payback” for western “arrogance”, according to The Sunday Times.
The paper claims to have unearthed “dozens of occasions” since 9/11 where he used acts of Islamist terror to blame or criticise Britain and the West while not condemning the attacks themselves.

The day after a video emerged showing the beheading of Mr Henning in October 2014 Mr Corbyn told a Stop the War rally: “I’m pleased that we started with a period of silence for Alan Henning… because we have to remember that the price of war, the price of intervention, the price of jingoism, is somebody else’s son, and somebody else’s daughter, being killed.”
It was also claimed Mr Corbyn had attended a wreath-laying at the grave of a Palestinian terrorist involved in the massacre of 11 athletes at the 1972 Olympic Games in Munich.
In an article for the Morning Star in October 2014 he described the ceremony where “wreaths were laid… on the graves of [those] killed by Mossad agents in Paris”.

The reference, so the paper claims, is to the PLO agent Atef Bseiso who was involved in the 1972 hostage-taking and massacre.
After the London suicide bombing of July 7, 2005, when 52 people lost their lives, Mr Corbyn is said to have argued: “We have to recognise that the security of this country is at risk… because of the way we inflict an insecurity on so many other people around the world.”
In addition, the paper claims in June 2015 he said: “None of us are in favour of what ISIS are doing. But those groups don’t come from nowhere… If we in our arrogance decide that the only solution to every conflict around the world is for western troops to go in, bomb, destroy and occupy, then there is a payback.”

Mr Corbyn also wrote an article for the Socialist Campaign Group News, the journal of Labour’s hard-left MPs, in the months after 9/11, where he condemned the attacks but also said the hijackers who flew aircraft into the World Trade Centre and Pentagon had acted with “an enormous amount of skill.”

A Labour Party spokesman said: “As Jeremy said in his speech on Friday, blame lies with the terrorists. Mr Corbyn said: ‘Protecting this country requires us to be both strong against terrorism and strong against the causes of terrorism. The blame is with the terrorists, but if we are to protect our people we must be honest about what threatens our security.
‘Those causes certainly cannot be reduced to foreign policy decisions alone. Over the past fifteen years or so, a sub-culture of often suicidal violence has developed amongst a tiny minority of, mainly young, men, falsely drawing authority fr
