Unicef: Lives of UK children improving, says UNICEF

9 April 2013 Last updated at 23:35 BST

Britain's children were described as the unhappiest in the developed world by the United Nations six years ago but now the organisation has now released a new study suggesting children's lives in the UK are improving.

Britain came bottom of a Unicef league table in 2007 comparing child well-being in wealthy countries but the BBC has exclusive access to the latest report which reveals improvements to children's lives - although there are warnings of persistent problems.
