Government costings laid out for new legislation aimed at improving the lives of young people have been defended by Scotland's Children's Minister Aileen Campbell following "serious concerns" from MSPs.

Ms Campbell faced cross-party scrutiny over the financial aspects of the Children and Young People Bill during an appearance at Holyrood's Education Committee.

The legislation includes provisions to increase free childcare for two-year-olds in the care system as well as all three and four-year-olds.

It wants a "named person" - such as a health visitor or teacher - to act as a key point of contact, put in place for every child as part of the Scottish Government's Getting it Right for Every Child approach.
