SINN Fein has welcomed singer Sinead O'Connor's membership application to the party despite her criticism of senior figures including Gerry Adams.
The singer confirmed on her Facebook page that she had signed up to the party because she is concerned about the country's sovereignty.
After being confronted with criticism from some of her followers, she defended her allegiance.
"For anyone who is confused, Sinn Fein is no longer associated with the use of violence," she wrote online.
Sinn Fein said it welcomed O'Connor's application and confirmed it is processing it.
O'Connor said Sinn Fein may oppose her beliefs on who should lead the party.
"I might not even be the kind of person they want, because I'm gonna write here that I feel the elders of Sinn Fein are going to have to make 'the supreme sacrifice' and step down shortly in the same way the last Pope did," she said.
"It was the smart thing for him to do because his association in people's minds with frightful things meant the Church were losing bums on seats, if I may use a showbiz term. And now they have barely a seat to spare."
A party spokesman said O'Connor would be able to have a say in the leadership of the party at its annual Ard Fheis.
"We welcome Sinead O'Connor's application to join Sinn Fein," he said.
"The membership of the party selects the Sinn Fein leadership every year at our Ard Fheis. As a member, Sinead would have an equal say in that process."
"We look forward to working with Sinead in an effort to deliver the changes so badly needed in Ireland."
However, O'Connor said that support for the party would grow if there was a change at the helm.
"There'd be a zillion per cent increase in membership of Sinn Fein if the leadership were handed over to those born from 1983/1985 onward and no one associated in people's minds with frightful things," she said.
Sinn Fein said the current leadership has been crucial to the party's growth.
"Support for Sinn Fein in this State has grown considerably since Gerry Adams was elected as a TD," said the spokesman.
