EX-LABOUR staffer Emilie Oldknow has lost her legal bid to force the party to say who leaked its internal report into the handling of allegations of anti-semitism.

In a ruling in the High Court in London today, Ms Justice Tipples refused Ms Oldknow’s application for an order forcing Labour to disclose who the party “reasonably believes” was responsible for the leak.

At a remote hearing last week, five anonymous individuals who deny any responsibility for the leak and who are supported by the trade union Unite, attempted to intervene in the Ms Oldknow’s application after they were told by Labour that they were “likely to be affected” if Ms Oldknow’s application was successful.
