New Ukip leader Henry Bolton has Nigel Farage's endorsement and members will be relieved Anne Marie Waters wasn't elected, according to a political commentator.
Speaking immediately after the announcement, Bolton said pressuring Theresa May's government into a hard Brexit will be UKIP's "core task" under his stewardship.
In a recent YouTube campaign film, he complained that "we have gone down the road of mediocracy and compromise, we don't like the idea of excelling of anything because we worry that it implies that somebody is less good".
The new UKIP leader will hold a press conference when the leadership result is announced and deliver a speech to members in Torquay on Friday. The most obvious way for the party to regain its mojo would be if Theresa May (or a new Conservative leader) sought to negotiate a close relationship with the European Union by, say, remaining in the single market.
Indeed, Mr Bolton had said that UKIP was in danger of becoming the "UK Nazi Party" if it plumped for Ms Waters (Ms Waters herself has vigorously denied this sort of claim).
Henry Bolton has been announced as Ukip's new leaderWho is Henry Bolton? A former soldier, Bolton is a one-time Lib Dem member who has worked as an European Union common defence strategist. Mr Farage today tweeted that he was "delighted", adding that Mr Bolton is "a man of real substance".
"Even last week, the clear divisions within the party could be seen here in Kent, as Mr Bolton and Chris Wells, the leader of Ukip's only council in the country in Thanet, publicly clashed over the future of Manston airport and the general running of the council".
This led to the resignation of the party's then leader Paul Nuttall.
He has denied reports he will quit the party to set up a new movement if Ms Waters is elected.
His predecessor Diane James, who replaced Nigel Farage, lasted just 18 days in the job.
Paul Nuttall quit as UKIP leader after the general election, which saw its vote share shrink to 1.8% at the general election from 12.6% in 2015.
