New Ukip leader Paul Nuttall said his election is the start of a new era for the party.
In his acceptance speech, the former deputy leader told supporters: "This is day zero, it's a new beginning.
"I have been there every step of the way. I have not just talked the talk, I've walked the walk.
"I will finish by saying; Ukip's future is bright, but for it to be so, Ukip must unite.
"And today's result has ensured that it will. There's a lot to do ladies and gentlemen, my friends, my colleagues, my brothers and sisters in Ukip.
"Let's get out there and let's get cracking!"
Nigel Farage has promised not to be "a back seat driver" now new Ukip leader Paul Nuttall has been elected.
The outgoing leader said Ukip was in a good position to thrive under its new head.
"I think everything is to play for and I am happy and confident that I'm handing this over at a good time," he said.
Mr Farage said he would serve out his term in the European Parliament until 2019.
But more imminently, he was this week "going off to the USA - but you will understand, purely as a tourist".
