A former president of Belfast Chamber of Commerce has joined Ukip.
Joe Jordan has had a long and successful career in property.
He headed the organisation representing local retailers during the loyalist protest against restrictions on the flying of the Union flag from Belfast City Hall which devastated trade.
The CBI estimated the downturn over the festive period in 2012 at £15 million.
Mr Jordan has also hit out at the increased number of bus lanes in the city centre, which he claimed contributed to falling numbers of shoppers and brought chaos to the morning commute.
He said: "I am delighted to be joining Ukip here in Northern Ireland. I have had a long career in business and during my term as president of the Belfast Chamber of Commerce, I dealt with many of our local politicians on a regular basis.
"When I recently made the decision to get involved in politics, there was only ever going to be one home for me, and that was Ukip."
A Newtownabbey councillor, former DUP representative Robert Hill, has also joined Ukip.
The party's leader in Northern Ireland, David McNarry, said the organisation was growing every day.
"I am very pleased that Joe has made the decision to join Ukip today, and I am confident that his experience in the business world will be a great asset to us going forward.
"Joe and others are realising that Ukip can be a political home for those who want change, but are fed up with the tired old parties and the same old broken promises."
