Former television presenter Mike Nesbitt has been elected as the new leader of the Ulster Unionist Party.
Mr Nesbitt, 54, who is a married father of four, was elected by a ballot of party members in Belfast.
He defeated rival John McCallister by 536 votes to 129 following a fiercely-fought leadership battle which revolved around whether to take the UUP into opposition at Stormont.
Mr Nesbitt pledged to instil a new spirit among people in Northern Ireland.
"I want everyone in this country to get out of bed with a sense of purpose. I want this party to wake up with a sense of purpose," he said.
"I want us to reach out to become the party of choice for every pro-union voter in Northern Ireland, including those who still say they want a United Ireland, but privately accept there is no longer a single reason not to enjoy their continued membership of the United Kingdom."
Around 850 people attended today's party AGM in Belfast and around 660 voted.
