Asked of just under half of the sample only. Effect of prompt shown by comparing answers with this poll's standard referendum vote intention reading (Remain 38; Leave 42; DK 20).
Positive cultural prompt: "Britain shares important values with our European neighbours, such as freedom of speech, gender equality, the rule of law, and respect for liberal democracy. Amid a world that seems less stable, and where there are competing ideologies, European countries can better promote and protect their values by acting together, as members of the European Union (EU). For Britain, remaining in the EU would help defend its national culture, traditions and values.”
