Speaker Lindsay Hoyle broke down in tears today, while speaking about his daughter's suicide.
The Commons speaker spoke movingly about his experience of suicide while introducing members of the band New Order at an event in Parliament about suicide and depression.
The event marked the 42nd anniversary of the death of Ian Curtis, the singer of Joy Division, the band's earlier incarnation.
"When it happens, you never get over it," Speaker Hoyle said.
"For me personally the biggest shock ever was the death of my daughter Natalie in 2017. She was 28. I am still rocked to this day. I still cannot believe...that she's gone."
Pausing briefly to hold back tears, he went on: "It was a relationship that was toxic, that still makes no sense. How somebody that has so much to offer, and so much to give - who was the perfect auntie to my grandchildren. It is without doubt the hardest, most difficult...something I don't like to talk about because it's so personal."
Speaker Hoyle added: "Of course, life goes on, but what I would say is - it doesn't get easier, it's just not there as much. It certainly comes back, and it comes back when you don't expect it. So I know just how hard it is for anybody who suffers that personal tragedy."
He also revealed his family had been rocked by suicide a second time this year, when his brother-in-law took his own life in March this year.
Labour leader Sir Keir Starmer also attended the session and spoke about two colleagues who had killed themselves after suffering mental health problems.
He said: "I am someone in a public role but also a dad of two young children and I think it is important that we say clearly that there is no shame in finding life hard at times - there is no shame in that - and for saying so.
"I don't think there is a parent who doesn't worry about their kids growing up, and there shouldn't be a chief executive who doesn't worry about their workforce.
"This has got to be a two-way process where we all have a further part in this."
