Childline is announcing the national roll-out of its ambitious ChildLine Schools Service programme to all primary schools in the UK.
They will send a mentor to every primary school in the UK to encourage pupils to open up about bullying and abuse - at school or at home.
An average of two children in every primary school classroom has suffered from abuse or neglect and the majority of cases go undetected. Later this week the Children's Commissioner will publish a report into child exploitation by gangs and groups.
Esther Rantzen and Anna Williamson are here to tell us more.
