"We have promised today that the next Labour Government will deliver one million genuinely affordable homes over ten years, the majority of which will be for social rent."
The paper also pledges to scrap the current definition of 'affordable housing' which Labour says includes homes let at up to 80% of market rents and homes for sale up to £450,000.
Labour says it wants to bring in a new definition, which links affordability to people's incomes.
Jeremy Corbyn said: "We have promised today that the next Labour Government will deliver one million genuinely affordable homes over ten years, the majority of which will be for social rent.
"And that we will dismiss the Tories farcical definition of affordable housing for the sham that it is, replacing it with a definition that understands that whether housing is affordable or not depends on how much people earn, not how much speculators have flooded property markets.
"This Green Paper sets out many of the radical measures needed, transforming the planning system and ending the “viability” loophole so that commercial developers aren’t let off the hook; giving councils new powers to acquire land to build on and better use land the public already owns; and the financial backing to actually deliver, which means the ability to borrow to build restored to all councils; and extra support from central government too."
