Giving children smartphones is the same as giving them cigarettes, shadow education secretary Laura Trott has said.

Renewing her call for ministers to ban phones in schools, she said they were just as inappropriate for pupils as tobacco.

And she also criticised the Government over plans to have screen-based testing for Reception children, saying it ‘normalises’ tablets.

Mrs Trott has forbidden her own three children from owning a smartphone until they are 16, and believes other parents should do the same.

Yesterday, she said schools implementing blanket bans would make it easier for families to follow suit at home.
