But there is nothing to be gained from the old strategies of pitting one community against another based on crude calculations of which will deliver the most votes. Instead, Labour must build a broad coalition of support, spanning geographical divides, social class and, yes, ethnicity. When people of mixed race, such as my children, constitute Britain’s fastest growing minority group, any narrative that focuses on traditional ethnic dividing lines is doomed to fail. Even the Conservative Party, which has long had a problem when it comes to race, has a new intake of ethnic minority MPs and is slowly beginning to win more support from non-white voters.
