Henry Bolton has been elected the new leader of Ukip following Paul Nuttall's resignation, beating Anne Marie Waters into second place.
Bolton, a former Liberal Democrat parliamentary candidate, received a total of 3,874 votes (29%) and becomes the fourth party leader in just over a year. Nuttall stood down following June's general election.
A former member of the British Army, Bolton previously stood as Ukip candidate Police and Crime Commissioner in Kent in 2016 and was awarded an OBE in 2013 for services to international security and stabilisation.
In his victory speech at Ukip conference in Torquay, Bolton said: "I do not see myself now as being simply your leader.
"I see myself as serving this party. You are the party, not me. This party needs to serve its country.
"Without being united we cannot lead, we cannot lead the nation and we cannot hold the Government to account and we cannot achieve our core purpose at all."
He added: "Brexit is our core task. However it is not the end of the line. When we leave the European Union that is not the end of the story."
Former leader Nigel Farage said he is "delighted" that Bolton won the election, describing him as a "man of real substance".
Bolton's name was not mentioned much during the election campaign which was dominated by Waters.
Bolton previously warned that Ukip would descend into the "UK Nazi party" if far-right anti-Islam candidate Waters was elected leader.
Speaking ahead of the result, former leadership hopeful Steven Woolfe told IBTimes UK a Waters leadership would be the "final nail in the coffin" for the party which has "nosedived" in recent months.
Several MEPs also threatened to quit if Waters won, with Farage also saying he would consider forming a new party.
Ukip failed to win any seats at the last election, with their then leader Nutall coming third in Boston and Skegness. Its total vote share fell from 12.9% in 2015 to just 1.8% in June.
Married with three children, Bolton's wife Tatiana Smurova-Bolton gave birth to their second child Victoria on a train to St Pancras station.
