Fathers have until Monday to contribute letters for a project spearheaded by Adolescence creator and star Stephen Graham.

The Emmy-winning actor is inviting people to share their experiences of manhood and raising boys for a book called Letters to Our Sons, inspired by his Netflix hit series.

Graham has contributed a letter to his own son for the project, which is run in conjunction with Brighton psychology lecturer Orly Klein and due to be published in October.

Sam Zindell, who submitted a letter to his 12-year-old, said he wanted to “impart some wisdom from my lived experience and my deep understanding of my own son”.
