The Social Market Foundation has urged the Government to put a penny on tax to add momentum to its plans to tackle child poverty.
The foundation outlines its argument in Overcoming disadvantage - An agenda for the next 20 years, a report commissioned by the Joseph Rowntree Foundation. "If the case for extra spending can be made for the NHS, why not for child poverty?" asks research fellow Roger Wicks.
The Social Market Foundation was one of five think-tanks that contributed to the report, which marks the start of the Joseph Rowntree Foundation's centenary.
In its contribution, the IPPR called on the Government to make tax increases the central plank of its anti-poverty strategy rather than rely on stealth measures such as increasing National Insurance payments.
Policy Exchange, the Scottish Council Foundation and the Institute of Welsh Affairs also submitted views to the report.
Lord Best, director of the Joseph Rowntree Foundation, said the think-tanks' views "pave the way for a political consensus about the value of tackling poverty that would have been unthinkable a decade ago".
