Just a quick catch up on this story;
Mr Wells accused party leader Arlene Foster of not standing by him.
“Peter Robinson made the commitment that I would return,” the South Down MLA said.
“Then Arlene took over as leader and Arlene, as leader of the party officers, ignored my two written requests for that commitment to be honoured,” he added.
Former DUP Leader Peter Robinson spoke to Nolan today about the topic which is worth a listen and analysis from Allison Morris and Malachy O’Doherty
