The Irish singer passed away on July 26 aged 56 last year, where she was found unresponsive in her home by police. She was laid to rest at a ceremony in the Irish town of Bray last August, with Bob Geldof and Bono among those paying tribute at her funeral.

Coroners confirmed in January this year that O’Connor had died of natural causes, but now the exact causes of her death have been released.

According to the Irish Independent, the death certificate (registered by her ex-husband John Reynolds) states that O’Connor died due to chronic obstructive pulmonary disease (COPD) and asthma.

The certificate also stated that O’Connor had also reportedly been suffering from “a lower-grade respiratory tract infection”. The singer’s death was certified by Julian Morris, senior coroner for Inner South London, upon the completion of a post-mortem examination without inquest.

Since O’Connor’s death, tributes have flooded in from the likes of Garbage, Michael Stipe and Ice-T.

Billy Corgan has also recently opened up about his friendship with Sinéad O’Connor, hailing her as “such an incredible talent”.

“People realise now that we lost someone who probably should have gotten more attention and support when she was here,” he said. “Because her gift was so rare. And her gift had a lot to do with her pathos. Her incredible gift of singing had a direct line to her heart. That’s so rare in singers. Most singers are actors. Sinéad was not an actor.”

In other news, a Dublin wax museum has apologised and removed their Sinéad O’Connor figure after backlash.
