The Child Poverty Bill was introduced to the House of Commons on 11th June 2009 as Bill 112 Session 2008-09. "The Bill would provide a statutory basis to the commitment made by the Government in 1999 to eradicate child poverty by 2020." It "places a duty on the Secretary of State to meet four United Kingdom-wide income poverty targets by the end of the financial year 2020".
These are Relative poverty; Combined low income and material deprivation; Persistent poverty; and Absolute poverty. The progress of the Bill can be followed from this Parliament web page and the full text of the document can be accessed in html or PDF format.
