Councillor Dave Proudlove, Labour councillor for Biddulph West, was one of those who undertook the training.
He said he lost a close friend to suicide some years ago, adding: “He was the type of person you would not have expected it to have happened to.”
Proudlove said the training had been “incredibly useful”, especially in teaching him how to spot signs of mental illness, along with “the ability to listen”.
“When I say listen, I don’t mean hear what someone’s got to say, I mean genuinely listen,” he added.
“The training is one of the best things I’ve ever done and I urge anybody who has the opportunity to do it… it could help save somebody’s life.”
