Two mothers are challenging the government in court over the Universal Credit (UC) two-child benefit policy.
That two-child cap prevents parents from claiming the child element of UC or child tax credit for a third or subsequent child.
The women, who cannot be identified, had two or more children non-consensually in relationships that began when they were teenagers.
A non-consensual conception exception to the two-child cap, sometimes referred to as the rape clause, allows for financial support for a child conceived non-consensually but only if that child is the third or subsequent child.
