Sir Keir Starmer has said it is "not easy" for young men "growing up in this day and age", in an open letter to his son to marking International Men's Day.
The prime minister urged men to talk openly about their mental health, reflecting on his strained relationship with his own father who he "never really spoke" to.
His comments come as the government launched England's first men's health strategy, aimed at tackling issues predominantly faced by men such as suicide, alcohol abuse and problem gambling.
In the letter to his 17-year-old son, who he has not publicly named, Sir Keir said there were "pressures on young men that are difficult to talk about".
