Labour urged again to vow to scrap Tories’ two-child benefit limit

Exclusive: Data shows policy, deepening poverty among low-income families, affects about 1.5 million children

Labour has come under fresh pressure to vow to scrap the two-child benefit cap after it emerged one in four children in some of England and Wales's poorest parliamentary constituencies live in families left at least 3,000 a year out of pocket as a result of the policy.

The party's stance on the policy, which critics say has been a major driver of deepening poverty among low-income families, is estimated to affect about 1.5 million children and is seen by some in Labour as an indicator of the strength of its determination to tackle child poverty.
