Addressing an audience of MPs and grassroots activists, which also included Nigel Farage, Ms Truss warned the political “landscape has shifted to the Left”.
She said that “the system is actively working to stop” Conservative politicians from pursuing Right-wing ideas that would shrink the size and role of the state.
“Conservatives really need to be thinking about how we change the system itself and how we create the political weather that enables these policies to happen,” she said.
‘Damaging divide’
Ms Truss warned there was now a “damaging divide” between those who ran the country and ordinary voters who “think the wokery that’s going on is nonsense”.
“I’m afraid we have not taken on the Left enough. The Left don’t just compete with us at the ballot box now, they also work to take over our institutions,” she said.
“The fundamental issue is that for years and years and years, and I think it goes back two decades, Conservatives have not taken on the Left-wing extremists.”
Ms Truss said the answer was to “galvanise our Conservative forces” and find Right-wing candidates “prepared to put their heads above the – people who agree with us but don’t want to admit it because they think it’s not acceptable in their place of work, at their school.
“This fight is not going to be easy. The Left have been on the march. They have been on the march in our institutions, in our corporate world, they are on the march globally.
“They are actively organising. But I believe this fight is important because I believe it is only through Conservative values that we will give the people of Britain what they want.”
The Popular Conservatives has been set up to help more Right-wing candidates be selected to run for Parliament at the next election and beyond.
It launched with a four-point manifesto to introduce “robust” border controls, end net zero “zealotry”, crack down on the nanny state and cut taxes and red tape.
Mr Farage, who proved one of the star attractions at the event, said he agreed with the group’s aims but that they would not be delivered by the Tories.
He said that “only Reform will offer this at the coming election” and quashed speculation that he may be planning to rejoin the Conservatives soon.
‘Grand revolution’
Sir Jacob told the gathering that farmers’ protests across Europe showed there was a “grand revolution going on” among voters against global elites.
In his speech, he warned that international bodies like the World Health Organization, the EU and the Cop climate summit “limit our freedom for manoeuvre”.
The former business secretary said: “The age of Davos man is over, of international cabals and quangos telling hundreds of millions of people how to lead their lives.
“It is not just in this country that people are entirely fed up with this internationalist, unaccountable approach to governing.
“We have to restore power to our democratic institutions and take it away from those that seek to override democracy.
Sir Jacob hit out at the “unaccountable, the faceless, the bureaucrat and the pious platitudes of pompous politicians which have been running this country for too long”.
Mr Anderson, who quit his role as Tory deputy chairman to rebel over the Rwanda Bill, said politicians were “out of touch with the public” on net zero.
He said that voters in his constituency of Ashfield, Nottinghamshire, were more concerned about rising energy and fuel bills than hitting carbon targets.
Mr Anderson said that he had suggested allowing people to opt out of paying green levies on their electricity and gas bills, but that the idea had been dismissed.
Voters saw Cop summits as “a load of rich people flying into an exotic country in private jets to tell poor people they have got to pay for the mistakes they have made”, he said, adding: “I can’t argue with that.”
