SINN Féin have secured three seats in the Glengormley area of Antrim and Newtownabbey Council for the first time.
With four gains on the Council, Sinn Féin are now the second largest party, with nine seats, only four seats behind the DUP on 13.
New candidate Eamonn McLaughlin was elected alongside sitting councillors Rosie Kinnear and Michael Goodman. The Sinn Féin gain was at the expense of SDLP's long-serving councillor Noreen McClelland, who has represented the area since 2001.
DUP councillor Alison Bennington topped the poll and the party retained their second seat through Paula Bradley, former Deputy Leader of the party.
Alliance councillor Julian McGrath and UUP councillor Mark Cosgrove also retained their seats in Glengormley DEA.
Speaking about securing a historic third seat for Sinn Féin in Glengormley, Eamonn said: "I am honoured to have been elected to Antrim and Newtownabbey Council by the people of Glengormley Urban. I want to thank every person who gave me their vote.
"Sinn Féin went into this campaign with a commitment to work for all, and I look forward to working with my colleagues to represent the people of this area and deliver first-class council services.
"This election was an opportunity to send a signal that it is time to get the Assembly up and running, and it is becoming clear from today’s results that this is what the majority of voters want."
Poll-topper Alison Bennington was delighted with her re-election.
"It has been a pleasure to serve the people of Glengormley Urban for the last four years, delivering on issues that matter to you," she said.
"It is also my pleasure to serve you for another four years. Those that voted for me I want to say a huge thank you to you all. I am here to fulfill the mandate you gave me."
