There is a ritual of withholding all criticism when someone from an ethnic minority takes a position of power. That ritual has now become farceSo here we are. Kemi Badenoch is the leader of the Conservative party. That’s another couple of firsts that the Tories have beaten Labour to. So far, the Conservatives have elected the first Asian leader and prime minister, and the first female Black leader of any major British political party.But as these firsts started to come quicker and closer together – we now have a brown party leader handing over to a Black one – two things have happened. One, the politics of the party has become more unhinged and its electoral record has tanked. And two, the profile of these mould-breaking new leaders has become more extreme. The two are not unrelated to the success of ethnic minorities in the Tory party. I am sorry to point this out, because there is a sort of ritual now that must be observed when the Tories do well on diversity: you must not speak ill of a person of colour who has been elected to a position of leadership for the first time, and the significance of that moment, above all else, should be respected.Nesrine Malik is a Guardian columnistDo you have an opinion on the issues raised in this article?
