Head of Child Protection Operations at the NSPCC, John Cameron, says children have a "greater likelihood" to be involved in criminal and anti-social behaviour if "they have been in receipt of smacking as a standard form of parenting".
Speaking with ITV News, Mr Cameron said smacking does not have a positive, long-term impact on children.
"This is not about prosecuting, persecuting and criminalising parents, but it's about giving a very strong message in our society that children should have the same rights as adults in law to be protected from physical assaults," he said.
