Central to the UK’s Referendum on EU membership, immigration concerns underpinned support for Leave. This article examines ethnic minority support for Brexit, comparing their immigration attitudes with white British voters. Why immigrants and ethnic minorities would support immigration controls through voting Leave presents a theoretical puzzle with existing research finding they generally hold positive attitudes to immigration. Drawing on focus groups and interviews, I find opposition to Eastern European immigration motivated ethnic minority Leave support, who bolstered their own position as “good” immigrants while denigrating Eastern Europeans as “bad” immigrants. This echoes emerging trends of minoritized groups opposing newer migrants, including increased Latino/x support for Trump in 2024. White British Leave voters, however, rarely distinguished between EU and non-EU migrants, often including British ethnic minorities in their “mental image” of immigrants. Thus, tighter borders may do little to quell qualms over immigration which (partly) reflect concerns over rising racial diversity.
