Later he became an East Antrim MLA and served as Alliance leader between 1998 and 2001.
“My thoughts and prayers today are with Sean’s family and friends,” said Ms Long.
She added: “But today, Alliance has also lost a part of our history.
“Sean showed leadership at a time when the party needed it, and we will always be grateful to him for that.
“Known for getting things done, Sean was a dedicated public servant who delivered for everyone in Carrickfergus as a councillor and then the wider East Antrim area when he became an MLA, a role he was delighted to take on.

“In later years, Sean’s passion for Alliance and Northern Ireland as a whole continued, and I was delighted he was well enough to join us at conference just last year.”
DUP leader Gavin Robinson said Mr Neeson had been a “strong voice for his constituents” as a political leader.
He said: “He was a passionate advocate for the beliefs and principles that guided him.
“His respectful approach earned him recognition across the political spectrum.
“We extend our deepest sympathy to his family and friends, and to all in the Alliance Party who mourn his passing today.”
Stewart Dickson, an Alliance Party colleague of Mr Neeson on Carrickfergus Council and as an East Antrim MLA, said he was “saddened to hear of the death of my good friend”.
I’m deeply saddened to learn of the passing of Sean Neeson.
