1) Eligibility to vote in British elections extends to both British and Commonwealth citizens, though some countries do not allow dual citizenship. Access to British citizenship has become more restrictive over time. 2) Registration rates among ethnic groups in Britain are high, around 80%, though the move to individual registration may present a new barrier. 3) Turnout rates among registered voters of all ethnic groups, including white British, are similar, around 75-80%, indicating that registration rather than citizenship is the main barrier to voting.
