A 16-year-old girl, Sobia, has been sent home from school in Manchester for refusing to wear school uniform.
Her headteacher, Dame Jean Else, has told her she is not allowed to wear the traditional Muslim dress.
About 200 Muslim sixth-formers wear business-style suits to the school. These suits were agreed with the Commission for Racial Equality.
Everyone who wants to go to her school has to agree to wear the uniform before they start.
