Labour is the new "nasty party", Theresa May claimed as she made her pitch for the Tories to be the natural home for working-class voters.
The Prime Minister, who once told the Conservatives that they were viewed as the "nasty party", used her keynote conference speech to condemn Jeremy Corbyn's "divisive" Labour.
She told activists in Birmingham that she would "put the power of government squarely at the service of ordinary working-class people".
May said: "Only we can do it. Because the main lesson I take from their conference last week is that the Labour Party is not just divided, but divisive.
"Determined to pit one against another. To pursue vendettas and settle scores. And to embrace the politics of pointless protest that simply pulls people further apart.
"That's what Labour stands for today. Fighting among themselves. Abusing their own MPs. Threatening to end their careers. Tolerating anti-Semitism and supporting voices of hate.
"You know what some people call them?
"The nasty party."
Her comments were a deliberate reference to the tough message she delivered to her own party when she was Tory chairwoman in 2002.
May continued: "With Labour divided, divisive and out of touch, we have a responsibility to step up, represent and govern for the whole nation.
"So where Labour build barriers, we will build bridges.
"That means tackling unfairness and injustice, and shifting the balance of Britain decisively in favour of ordinary working-class people.
"Giving them access to the opportunities that are too often the preserve of the privileged few.
"Putting fairness at the heart of our agenda and creating a country in which hard work is rewarded and talent is welcome.
"A nation where contribution matters more than entitlement. Merit matters more than wealth.
"A confident, global Britain that doesn't turn its back on globalisation but ensures the benefits are shared by all.
"A country that is prosperous and secure, so every person may share in the wealth of the nation and live their life free from fear.
"That's what I mean by a country that works for everyone."
