Jeremy Corbyn is set to announce plans to radically reshape the UK economy, creating 400,000 skilled posts in a "green jobs revolution."
In his keynote speech to Labour’s annual conference in Liverpool on Wednesday, Corbyn will denounce “greed-is good capitalism” and accuse “the political and corporate establishment” of propping up the financial system which caused misery to millions following the crash of 2008.
He will also say that Labour is ready to deliver “the radical plan we need to rebuild and transform Britain”, telling delegates: “The old way of running things isn’t working anymore.”
Mr Corbyn will say Britain needs a Government “committed to investing in renewables, in jobs and in training” and will promise large-scale public and private investment in wind and solar power, as well as subsidies to make all homes energy efficient.
Changes to planning guidance will aim to encourage private investment to double onshore wind power over 12 years, while offshore wind will be increased seven-fold and solar power threefold.
Corbyn’s speech comes at the end of a four-day conference which has been dominated by Brexit.
The Labour leader admitted to ITV News that delaying the start of Brexit next March is an option.
And the party voted to keep open the option of a second referendum.
But the Labour leader and shadow chancellor John McDonnell also set out a range of policies to reverse inequalities in wealth and economic power.
These have ranged from workers in the boardroom to employee shareholding funds and new taxes on second homes.
They sparked warnings from the CBI that Labour risks “cracking the foundations of this country’s prosperity”.
But Corbyn will say it is “essential” to change the system which has seen growing inequality, job insecurity and in-work poverty over the past decade.
Corbyn’s comments risk being seen as an attack on former Labour prime minister Gordon Brown, who led the global response to the financial crash in 2008 with massive intervention to shore up the banks.
But aides insisted that Corbyn regarded the ex-PM’s decision to take action to avert a collapse in the financial system as “absolutely correct”, though he had reservations about the subsequent package of support for banks, quantitative easing and interest rate cuts which saw much of the benefit of bail-outs go to the wealthy while poorer parts of society suffered austerity.
Setting out his plans to invest in green jobs, Corbyn will say: “There is no bigger threat facing humanity than climate change. We must lead by example.”
Labour’s plans would see £12.8 billion invested in an insulation programme over five years, with means-tested subsidies for low-income owner-occupiers and social housing and zero interest loans for home-owners and landlords who are able to pay.
Universal energy efficiency measures – including retrofitting of old properties – would reduce heat demand from buildings by a quarter.
The party aims to increase the share of electricity coming from low carbon or renewable sources from 50% to 85% and the share of heat from almost nothing to 44% by 2030, as part of a drive to cut 60% of greenhouse gas emissions by that date and reach zero emissions by 2050.
Corbyn will say: “Our energy plans would make Britain the only developed country outside Scandinavia to be on track to meet our climate change obligations.
“That means working with unions representing the workforce to ensure jobs and skills are protected as we move towards a low-carbon economy.
“And it means working with industry to change the way we build, and to train the workforce to retrofit homes and work in the industries we will build.
“It needs a government committed to investing in renewables, in jobs and in training."
