Labour is ready for another election after June's vote "changed politics in this country", Jeremy Corbyn has declared.
The Labour leader said his party now represented "the mainstream" of British politics with the Government in "disarray".
Before the party's conference, Mr Corbyn gave details of Labour's preparations for an election - including plans to target top Tories including Amber Rudd, Boris Johnson and Iain Duncan Smith.
Labour gained 30 seats in the June general election, closing the gap on the Tories to 56 as Theresa May lost her majority.
But the Labour leader - whose position is secure as the party prepares to gather for its Brighton conference - said he was ready to take on the Tories again, with key figures in his sights.
He told the Guardian: "The election has changed politics in this country. We are now the mainstream.
"The Government lacks any sense of direction. They are hiding behind parliamentary power grabs to avoid scrutiny."
Vowing to "challenge the Tories at every step" he added: "It is a government that is in disarray. We will keep up pressure in Parliament."
Mr Corbyn, who plans to restart his tour of marginal constituencies, said: "We are ready for an election and we will keep on demanding that this takes place in Parliament."
He said Labour was already selecting candidates in key seats and putting detailed policy papers together.
"We are preparing by campaigning over the country, continuing to challenge austerity," he said.
"And we have made enormous progress in changing the political debate. The campaign showed what Labour can do when we go out with a message of hope."
The Labour leader wants to hold rallies in seats held by senior Tories including Home Secretary Ms Rudd, who has a wafer-thin majority in Hastings and Rye, Education Secretary Justine Greening, Welsh Secretary Alun Cairns and ex-leader Iain Duncan Smith, as well as targeting Mr Johnson's Uxbridge and Ruislip South - where the Foreign Secretary has a majority of 5,000.
The conference in Brighton, which starts on Sunday, now looks set to feature a speech from London mayor Sadiq Khan after he had initially been denied a platform appearance.
