Labour launched an investigation in April last year after Ms Abbott wrote in the Observer that Irish, Jewish and Traveller people “undoubtedly experience prejudice” which she said is “similar to racism”.
The letter added: “It is true that many types of white people with points of difference, such as redheads, can experience this prejudice.
“But they are not all their lives subject to racism.”
Ms Abbott apologised and withdrew her remarks shortly after they were published.
BBC Newsnight revealed earlier that the party’s investigation was completed in December 2023.
Labour’s National Executive Committee (NEC) issued her with a “formal warning” for “engaging in conduct that was in the opinion of the NEC, prejudicial and grossly detrimental to the Labour Party”.
It said it expected her to undertake an “online, e-learning module” which a source said was a two-hour antisemitism awareness course.
Ms Abbott did the module in February, after which it is understood she received an email from Labour’s chief whip acknowledging she had completed it.
However, as recently as Friday, Sir Keir had been saying the investigation into her comments was not “resolved”.
Prime Minister Rishi Sunak said Labour needed to “clear up” this issue.
“The Labour Party has been telling everybody this investigation into Diane Abbott is ongoing, it now appears it concluded months ago,” he said.
The Scottish National Party said Sir Keir’s treatment of Ms Abbott was “disgraceful” and “shows a total lack of judgement”.
