The British National Party was today barred from taking new members after a judge ruled its constitution could discriminate against non-white people.
Judge Paul Collins issued an injunction ordering the far right group to comply with race equality laws.
He said: “The membership list will have to be closed until then.”
Under the injunction, prospective BNP members will not in future have to be vetted at home before they are accepted.
Last month the BNP scrapped its whites-only policy in an attempt to avoid legal sanctions brought by the Equality and Human Rights Commission (EHRC).
But today at Central London County Court, Judge Collins ruled: “I hold that the BNP are likely to commit unlawful acts of discrimination within section 1b Race Relations Act 1976 in the terms on which they are prepared to admit persons to membership under the 12th addition of their constitution.”
