Anand Shukla, Chief Executive of Daycare Trust and the Family and Parenting Institute said:
"London is a city of contradictions - an economic power-house, but home to some of the poorest families in Britain. A quarter of the capitals children live in poverty, and rates of female unemployment are higher than anywhere else in the country.
"Childcare is as essential as food and heating for working families. Yet while wages stay still and childcare becomes more expensive, its increasingly difficult for parents - and mothers in particular - to make work pay.
"Not everyone is able to contemplate a private education for their child, and yet working families are being expected to pay more for their childs nursery place - an average of £14,000 per year - than the fees for a top private day school. This is happening at a time when family budgets are being squeezed to the limit by wage freezes and a drop in government help through the tax credit system."
