The upcoming equality bill will make the British National party's (BNP) membership criteria illegal, Harriet Harman has confirmed.
Speaking during business questions opposite Alan Duncan, Ms Harman responded to concerns about the election of two BNP MEPs last week in the European elections.
Ms Harman said she was "shocked and horrified" by their success but went on to say its constitution - which bars non-whites from membership – would become illegal once the equality bill was passed.
"There is no place for a political party in this country to have an apartheid constitution and the equality bill will prevent this from being the case," she said.
She added: "There is no place in British national life and democracy for a party that excludes people on the basis of the colour of their skin".
