A single mother has won compensation for sex discrimination from a lettings agency that refused to consider her as a tenant because she was claiming benefits.  Rosie Keogh successfully argued that a blanket No DSS ban discriminated against women as they are more likely than single men to be claiming housing benefit, particularly if they have children. The case was settled out of court and has not set legal precedence however it has established that the practice could be considered indirect sex discrimination.
