Former Alliance party councillor Vasundhara Kamble has joined the DUP.
The announcement was made at the party's annual conference on Saturday, when it was unveiled former UUP councillor John Scott had also joined.
The pair were given a standing ovation by the crowd gathered at the La Mon House Hotel in Belfast.
Mrs Kamble quit her former party back in January alongside long-serving councillor Geraldine Rice.
She had been the Alliance party's only elected representative from a minority ethnic background, and alleged she experienced an "under-current of racism" in the party.
Councillor Kamble, who came to Northern Ireland from Mumbai in India, in 1995, had been an Alliance councillor for six years.
Speaking to the Belfast Telegraph at the time of her resignation, she accused the party of "snobbery" and said it was "a tight clique of elitist individuals".
Since then she has been serving as an independent councillor.
Councillor John Scott, formerly of the UUP, quit his party in September after declaring his unhappiness at the way it was being run to a gathering of Antrim and Newtownabbey Borough Council.
Speaking to the North Belfast News at the time, he said his issue was with the grouping within the council rather than the wider UUP.
