Deputy Prime Minister and Housing Secretary Angela Rayner said: "I will not run away from the tough choices to fix the housing crisis we inherited that has left thousands of families on housing waiting lists, allowed homelessness to spiral out of control, and stopped an entire generation from picking up the keys to their first home.
Writing in The Metro, Sir Keir said he knew there would be "huge opposition" to his latest plans, but that "for too long the NIMBYs and the naysayers have been able to clog up our systems so things can't get built".
More than 100 new towns could be built under the government's plans for the "largest housebuilding programme since the post-war era".
Sir Keir said: "We're urgently using all levers available to build the homes we need so more families can get on the housing ladder.
"As part of the largest housebuilding programme since the post-war era, our ambitious Plan for Change will transform the lives of working people, once again connecting the basic principle that if you work hard, you should get on.".
