"...[Corbyn] hosted the show Comment, on Press TV, the [official television] channel of the Islamic Republic of Iran. In 2009, Corbyn welcomed Dyab Abou Jahjah to the UK’s parliament. Jahjah is a political activist and publisher who became known for publishing, in 2006, a series of cartoons poking fun at the Holocaust. As late as 2013, Corbyn attended events organized by Paul Eisen, at that time known as an outspoken Holocaust denier. In 2012, he hosted the hate preacher Raed Salah at the House of Commons. In a sermon two years later, Salah—whom Corbyn had called a “very honored citizen” and invited for tea—expressed hope that Jerusalem would soon become “the capital of the global caliphate.“
"Corbyn also came publicly to the defense of Stephen Sizer, an Anglican vicar who, as he put it, “dared to speak out against Zionism".
And what could possibly be wrong with that?
