Sir Jeffrey Donaldson has been formally elected as leader of the Democratic Unionist Party (DUP).
He received a majority vote from 32 out of the party's 36 members which include MPs and Assembly members.
The Lagan Valley MP will be the fifth leader in the DUP's 50 years and its third in the last 50 days.
Arlene Foster, who led the party for over five years, stepped down at the end of April after over 20 DUP Assembly members and four MPs signed a letter voicing no-confidence in the leadership.
Edwin Poots then stepped into the position and lasted only 21 days in the midst of ongoing divisions in Northern Ireland's largest political party.
According to reports, Mr. Poots was not in attendance at the latest electoral college meeting - to which Sir Jeffrey explained that he had "prior commitments" and was a "busy man".
Donaldson said: "Four of my colleagues decided not to vote today, not to vote in favour of my leadership and I respect that, I respect their right to do so.”
He went on to say: "My task, the challenge for me, is to win the confidence of all our past, including the four who decided not to vote today in my favour.
"Our priority will be to right the wrong that has been done by the imposition of the Northern Ireland Protocol and to restore Northern Ireland's place fully within the UK internal market.
"Northern Ireland is given the right under the Act of Union to trade freely with the rest of our own country and all that we ask if for that right to be restored, that we can trade freely with the rest of the United Kingdom and continue to trade with our neighbours.
"And there must be a solution to that. We need to find that solution," he said.
