As of this morning the total membership of the party has been confirmed at 38,124.
Staff in the membership department once again worked over the weekend to catch up on the latest backlog of applications.
At the current rate of increase, UKIP membership is on course to top 40,000 by the end of July.
UKIP Director of Communications Patrick O’Flynn said: “This is a fantastic new total for membership of our party. There is no sign of the rate of growth slowing down and new applications are coming in all the time.
“If we do well in the European elections there is every prospect of an even bigger membership surge following over the summer. These are very exciting times for the party.”
