Can the Conservatives ever win over non-white support? Black, Asian and minority ethnic communities are as diverse in their values and beliefs as the rest of the population, yet there is a history of ethnic minority voters overwhelmingly supporting the Labour Party. Recent studies show that in 2017 three quarters continued to back Labour, while under a fifth voted for the Conservatives. Long-term this is a headache for the Tories, as the proportion of the population who identify as BAME is expected to double to between 20 and 30 percent over the next thirty years. Professor Rosie Campbell of King's College London looks at the potential political impact of ethnic minority voters and what the parties can do to do win the trust and votes of communities which may in future, decide who governs Britain.
