Jeremy Corbyn said the BBC Panorama documentary on anti-Semitism in the party has "many, many inaccuracies." He said the program took a "pre-set position" before it aired.
The Labor chief commented on a visit to the Durham Miners' Gala. He said, "I looked at the program and I felt that there were many, many inaccuracies in the program. The program took a fixed position on its own website before broadcasting. We have made very clear what our processes look like.
"Our party members have the right to be heard when they are accused, and our party members have the right to be supported, and they are supported."
Asked if he would publish Labor's response to the Equalities and Human Rights Commission's investigation into allegations of anti-Semitism in the party, Corbyn said the investigation had not yet taken place. However, he said he would cooperate fully with the Commission.
"Anti-Semitism is a poison, it's mean, it's wrong," he said. "It's a poison in our society and in every other society, it's not acceptable in any form."
Corbyn noted that anyone in the party who commits an act of anti-Semitism is faced with deprivation of membership or exclusion and "we have done that". He said, "We're investigating every case that crops up … There are less than 0.1% of our members ever involved in any charge, no matter how the problem was resolved."
The Labor Chief added, "We are working on it in a timely manner and I believe anyone who looks at our process will say that this is a robust process. Maybe we will invite other political parties to use the same care that we have adopted. "
Corbyn also joined Boris Johnson and Jeremy Hunt to defend the press by publishing diplomatic broadcasts sent by former British Ambassador to the United States, Kim Darroch.
The city police have launched a criminal investigation into the leak of messages sent to the e-mail on Sunday. The largest British police threatened the media with a criminal prosecution for publishing the broadcasts.
Corbyn said it was normal for the police to be involved. "If that had been the other way around and emails had leaked between the US embassy in London and Washington, I would be sure the US had a lot to say about it."
"Freedom of the press is of course crucial. There are rules and there is considerable protection for journalists who reveal something, and that is of course the right thing. "
