Jeremy Corbyn has claimed that 9/11 was "manipulated" to make it look like Osama Bin Laden was responsible to allow the West to go to war in Afghanistan.
In comments that will raise questions about his suitability to lead the Labour Party, Mr Corbyn appeared to blame George Bush and Tony Blair for using the September 11 attacks in New York to allow them to go to war.
In a series of further articles, Mr Corbyn also appears to endorse controversial conspiracy theories about a “New World Order”.
In an article for “Labour Briefing” in 1991, Mr Corbyn wrote: “We now know that the Gulf War was a curtain-raiser for the New World Order: the rich and powerful, white and western will be able to maintain the present economic order with free use of all the weapons they wish for.”
That same year, he said in Socialist Campaign Group News: “The aim of the war machine of the United States is to maintain a world order dominated by the banks and multinational companies of Europe and North America.”
