The Tories are stealing Ukip's "best ideas", the party's new leader Diane James has said.
Terming the prime minster "Magpie May", James, who takes over from Nigel Farage at the head of the Eurosceptic party, said Theresa May had stolen Ukip's policies, including the controversial grammar schools measures that have been much debated this week.
"Just remember where the best ideas - that you steal - where they came from and in all likelihood where they will come from again in the future," James said.
Speaking after her announcement as Ukip's new leader, James urged her party to prepare itself for the next general election, saying Ukip had "moved mountains on the political landscape" and was the "change movement of the United Kingdom".
Douglas Carswell has insisted he will "absolutely not" quit Ukip after Nigel Farage said he "really isn't doing anything for us".
With the election of Diane James, Ukip has tipped the gender balance in British politics, but true diversity is still some way off.
The grammar-educated former healthcare sector worker made her political name in defeat and holds Vladimir Putin up as a leadership mentor.
