Campaigners fighting government plans to appoint state guardians for every child in Scotland have taken their case to the Supreme Court.

Four charities and three individuals have lodged an appeal against controversial provisions for “named persons” set out in the Children and Young People (Scotland) Act 2014.

The No to Named Persons (NO2NP) pressure group argues that the legislation breaches data protection and human rights laws.

But last year three judges at the Court of Session in Edinburgh dismissed their concerns as “hyperbole”.

NO2NP, which includes representatives from the Christian Institute, Family Education Trust, the Young ME Sufferers Trust, and Christian Action Research and Education, has now taken its fight to the Supreme Court in London.

A two-day hearing has begun on Tuesday.

A single point of contact like a teacher or health visitor will be assigned to look out for the welfare of children under the Scottish Government’s "named persons" rules.

Holyrood says the service will act as a safety net to help families and children if they need it, speed up bureaucracy and save families from having to speak to multiple different services.
