I don’t think that government ministers with South Asian heritage and culture feel venomous hatred towards immigrants, I think they are just ambitious Tories.
If you are a dark skinned member of the Conservative Party you probably need to prove yourself more than most. You are already at a disadvantage just for not being a white and Christian.
With Zahawi, Braverman, and Sunak, you have a Muslim, a Buddhist, and a Hindu, I don’t know how well that goes down in local Conservative Associations but I can imagine a certain amount of unease among some. Especially as these are very senior ministers that we are talking about – not just local councillors.
