Sir Keir Starmer has come under pressure to remove Labor whip from MP Dawn Butler after she appeared to share a tweet describing Kemi Badenoch as a “member of the class of black collaborators of white supremacy”.

Ms Butler quickly deleted her retweet of a post by Nigerian-British author Nels Abbey responding to the prospect of Ms Badenoch becoming Tory leader, describing “Badenochism” as “white supremacy in the face of blackness”.

But she has been heavily criticized by Tory figures, with several calling for her to lose the Labor whip.

He said: “This will be a test to see if Keir Starmer removes the whip or effectively accepts Butler’s abhorrent endorsement of this smear.”

But on Sunday night, Labor showed no signs of taking the whip off Ms Butler.

Sir Keir has previously suspended the whip from Labor MPs in response to comments about black Tory politicians.

In 2022, he suspended Rupa Huq from the party for describing then-chancellor Kwasi Kwarteng as “shallow” black. Ms Huq apologized and reinstated the whip six months later.

Other Labor figures, including Sir Keir and Foreign Secretary David Lammy, hailed Ms Badenoch’s election as the first black leader of a major UK party as a historic moment.

In subsequent posts, Mr Abbey said his initial comments were “clearly satirical” and “intended as a sketch”, but defended Ms Butler saying she “might not salute the ancestry of a person of extreme right reactionary color”.

He added: “Because of things like this, which represent vehement political disagreement, it is both right and to be expected that many black people should not regard Badenoch (the opposition leader) as a ‘moment of pride in our nation’ in the same way as, say, Keir Starmer (or is politically mandated)’.
