Writer joins more than 100,000 parents who pledge to withhold smartphones until children are at least 14

The writer of Adolescence has backed the Smartphone Free Childhood group, which has received the support of more than 100,000 parents pledging to withhold smartphones from their children until they are at least 14.

Jack Thorne, co-writer of the Netflix drama about “incel” culture, said he supported the campaign’s “parent pact” – an online promise to wait until the end of year 9 before considering giving a child a smartphone.
