O'Connor's version of Prince's Nothing Compares 2 U has been played at rallies for the former president, who is hoping to be re-elected.

Together with label Chrysalis Records, her estate has demanded Mr Trump "desist from using her music immediately".

In a joint statement, they said O'Connor, who died aged 56 last July "lived by a fierce moral code defined by honesty, kindness, fairness, and decency towards her fellow human beings".

"It is no exaggeration to say that Sinead would have been disgusted, hurt and insulted to have her work misrepresented in this way by someone who she herself referred to as a 'biblical devil'," they continued.

"As the guardians of her legacy, we demand that Donald Trump and his associates desist from using her music immediately."

O'Connor's cover of Prince's song propelled her to stardom and spent weeks at number one in the UK singles chart.

The Dublin-born singer was known for speaking out on her mental health struggles and against the Catholic Church. In 2018, she converted to Islam and changed her name.

She died at her home in south London from natural causes on 26 July 2023, a coroner ruled.

Several artists have previously publicly called for Mr Trump to stop using their music for his campaigns, including Rihanna - who called Mr Trump's 2018 rallies "tragic" - Linkin Park and Aerosmith frontman Steven Tyler.

Mr Trump is currently on the campaign trail and looking to secure his place as the Republican nominee for the presidency, ahead of the US general election in November.

The former president is currently the frontrunner for the Republican nomination and his only remaining rival is former South Carolina governor Nikki Haley.
