The English Defense League says thousands of its members will march Saturday in Luton, a working-class town north of London with a history of racial tension.

Members of left-wing group Unite Against Fascism and Muslim organizations are expected to confront them, with riot police on hand to keep the two sides apart.

The English Defense League says it is a non-racist group set up to oppose the spread of militant Islam. But at previous demonstrations its members have clashed with police, chanted anti-Muslim slogans and made Nazi salutes.
