BBC bosses have released heartbreaking new footage of Professor Green .

In a trailer for upcoming documentary Suicide And Me, the British rapper opens up about losing his father Peter Manderson seven years ago.

"Suicide is the biggest killer of men under the age of 45," he says in the clip.

"It's not a topic anyone really wants to talk about. But I'd like to get a better understanding of why my dad did what he did. And I'd like to, bit by bit, remove the taboo that surrounds [suicide]."

In this new documentary, Professor Green - real name Stephen Manderson - sets out to uncover the truth behind his father's death and why suicide takes the lives of so many men in this country.

The hour-long programme will see him reconnecting with old family members as he opens up about his broken relationship with his dad.

While catching up with relatives, the rapper is shocked as he discovers that one of his father's brothers hanged himself while another died in a diabetic coma believed to have been self-inflicted.

Professor Green has previously admitted that he suffers with depression and believes the condition may be genetic.

Opening up about his battle with the illness, he said: “I never felt suicidal. Although I have been times when I’ve felt so anxious that I’ve wanted to get out of my skin.

“But I’ve never ever thought about how I would do it so I can’t say I have been suicidal. I’ve felt like I just wanted everything to stop which is very different from wanting to be dead.

"I can see how, for some people, those thoughts can lead to ‘the only way things can stop is by doing you know what’.

“But that’s not something I’ve ever veered towards.”

The Sunday Mirror has long been campaigning with Time to Change – and the charities Mind and Rethink Mental Illness – to help try to break down stigma surrounding mental health disorders .

Breaking the Mould: Professor Green Suicide and Me is on BBC THREE, Tuesday 27 October at 9pm.
