Labour leader Kezia Dugdale has called for the roll-out of the Scottish Government’s named person scheme to be “paused”, claiming the policy is an “absolute mess”.
Conservative leader Ruth Davidson has also urged the SNP to “press the pause button” on the scheme.
The named person legislation was passed at Holyrood in 2014, with Labour and the Liberal Democrats joining the SNP in backing it while Tory MSPs abstained.
Ms Dugdale said a full review of the policy is now needed so that concerns of parents can be addressed.
She said: “This entire process has been an absolute mess and it has caused a lot of anxiety for parents. Parents have lost confidence in the named person scheme.
“We support the principle behind this policy, which is that the children at risk of falling through the cracks get the support they need.
“But the introduction of the policy has been botched by the SNP – from the communication of this policy to parents to the way the legislation has been presented to Parliament.”
She added: “A Labour government will pause the process and ask the Children’s Commissioner to carry out a full review, so that the concerns of parents can be addressed.
“If improvements are recommended, then they will be implemented.
“The introduction of the named person scheme has been a shambles by the SNP and, as a result of that, what we are forgetting is that we need to make sure children who need extra support get that. That should be the priority.”
The scheme, brought in as part of the Children and Young People (Scotland) Act, will see every youngster under the age of 18 assigned a single point of contact, such as a teacher or health visitor, to look out for their welfare.
The Scottish Government said the service will act as a safety net to help families and children if they need it while opponents argue the move breaches the human rights of parents.
A poll conducted earlier this month found almost half of people in Scotland opposed the plan while less than a third supported it.
When asked if she would end the named person legislation, Ruth Davidson told BBC Radio Scotland’s Good Morning Scotland: “Yes, it was in our manifesto for last year’s election, it will be in our manifesto for this year’s election.
“We think the named person legislation is flawed, we want the Scottish Government to pause on it, so it does not introduce it to every family in Scotland from August, and to reassess this.
“We’ve opposed this at almost every turn.”
