The charities have issued a pocket-sized manifesto card which asks MPs to support the policies and urges voters to quiz their local candidates on their support for the five calls.

"We are spelling out what the political parties must do to show they really are committed to supporting and protecting children," said Mary Marsh, NSPCC Director.

"Children can't vote. We ask all voters to question their local candidates on their support for our five key calls and to use their vote to secure a safe and healthy future for our children. That's what our Full Stop Campaign is all about."

Barnardo's chief executive Roger Singleton added: "As the General Election approaches, we must ensure the main political parties give greater priority to the needs of those children who represent our most vulnerable and disadvantaged citizens.

"We welcome recent Government initiatives but the UK has a long way to go to get things right for its children and a real step change is needed to make a sustained difference to the lives of children and families."

Director of the Child Poverty Action Group, Martin Barnes, said: "Achieving real change and improvement in the lives of children requires a programme which is radical but practical and affordable."

Last year, the three charities prioduced 'a blueprint' for Government on children's issues Our children, their future - a manifesto which was endorsed by more than 50 children's organisations.

A version of the manifesto for Northern Ireland will be launched on April 3 in Belfast and a Welsh version Wales' children, our future was launched earlier this month.
