Two fathers have announced they will seek a judicial review of government guidance as part of a campaign to get smartphones banned in schools.
Will Orr-Ewing from Oxford and Pete Montgomery, who lives near Lancaster, have warned Education Secretary Bridget Phillipson, in a letter on Friday, that they plan to take legal action.
The pair have said the current guidance, which allows headteachers to decide how smartphones are used, is unlawful and unsafe for children.
The Department for Education (DfE) said schools already had the power to ban phones and it was bringing in "better protections" from harmful content through the Online Safety Act.
