It states that there was a failure to develop "detailed or coherent guidelines for investigating complaints based on social media conduct" and a failure to "implement the Macpherson principle of logging and investigating complaints of racism as racism".
Following what the report describes as a "systematic review" of all complaints received between November 2016 to February 2018, it claims investigations were initiated into only 34 of the more than 300 complaints received in relation to antisemitism.
"At least half of these warranted action, many of them in relation to very extreme forms of antisemitism, but were ignored. Almost all of these complaints were forwarded from one inbox to another, and many of them were identified as Labour members and sent to the Head of Disputes, Sam Matthews, for action", the report claims.
In a statement to Sky News responding to the leaked report, Sam Matthews said: "This latest episode comes as no surprise to me, as an effort by a disgruntled faction who are floundering in their attempts to blame others in order to distract from matters that will be investigated by the EHRC and the Courts.
"I hope Keir Starmer will stand by his commitment to undo the damage that they and their supporters have caused.

Mr Matthews continued: "The proper examination of the full evidence will show that as Head of Disputes and Acting Director, I did my level best to tackle the poison of anti-Jewish racism which was growing under Jeremy Corbyn's leadership.
"A highly selective, retrospective review of the Party's poor record, not deemed good enough for submission by the Party's own lawyers and conducted in the dying days of a Corbyn's leadership in order to justify their inaction, simply cannot be relied upon."
