Angered DUP members stormed out of a council meeting in "protest" during a debate on inviting the Taoiseach to Newry.
A notice of motion was brought forward by Cllr Gary Stokes of the SDLP to invite Irish premier Micheál Martin due to EU funding being spent in the district, which was then discussed in the chambers on Monday night.
Earlier during the same meeting, Cllr Alan Lewis, DUP, had put forward his own notice to request funding for public celebrations for the coronation of King Charles III.
