Citizens Advice Bureaux are being put on alert to look out for racist political campaigning and propaganda in the run-up to the European elections on June 10.
Guidance sent out to local bureaux highlights existing legislation on the incitement of racial hatred by parties and candidates, and how bureaux should respond.
The advice points out that, as registered charities in receipt of local authority funding, bureaux cannot be party political, but they should counter false information in literature and advertising.
Citizens Advice chief executive David Harker said: "If it is falsely claimed that local people can't get advice because of a drain on resources caused by asylum seekers, the organisation is entitled to publicly state that such claims are wrong."
Bureaux staff are advised to contact the police or the Monitoring Group, a national body supporting victims of racial harassment, if they encounter racist political activities.
