Boris Johnson is unveiling government plans to soften the economic impact of coronavirus with a promise to "build build build".
Speaking in the West Midlands, the prime minister will say he wants to use the coronavirus crisis "to tackle this country's great unresolved challenges".
As part of a "new deal", Mr Johnson is setting out plans to accelerate £5bn on infrastructure projects.
Labour has called for a "laser-like focus" on preventing job losses.
In April, the UK economy shrunk by a record 20.4% as a result of the spread of coronavirus and the subsequent lockdown measures.
Aiming to emulate the New Deal policies of the depression-era American President Franklin D. Roosevelt, Mr Johnson will say he wants a government that "puts its arms around people at a time of crisis".
In the aftermath of the Wall Street Crash of 1929, President Roosevelt launched one of the largest, most expensive US government programmes which included building schools, hospitals and dams.
In a bid to boost the country's financial outlook, Mr Johnson is pledging to put jobs and infrastructure at the centre of the government's economic growth with a commitment to "build, build, build".
Mr Johnson will say he wants to use the coronavirus crisis as an opportunity to "to build the homes, to fix the NHS, to tackle the skills crisis, to mend the indefensible gap in opportunity and productivity and connectivity between the regions of the UK".
"Too many parts of this country have felt left behind, neglected, unloved, as though someone had taken a strategic decision that their fate did not matter as much as the metropolis.
"And so I want you to know that this government not only has a vision to change this country for the better, we have a mission to unite and level up.
Projects in the £5bn investment plan include:
The government says it will bring forward funding to "accelerate" infrastructure projects in Scotland, Wales and Northern Ireland.
Scottish First Minister Nicola Sturgeon said the PM's plans fell "woefully short" of an economic recovery package recently announced in Germany.
"I also suspect there will be less to it than meets the eye in terms of genuinely new money," she tweeted.
Chancellor Rishi Sunak will provide an update on the economy next week, and in the autumn the government will publish a National Infrastructure Strategy.
Earlier, shadow chancellor Anneliese Dodds told BBC Breakfast Labour supported investment, but a "strong laser-like focus on unemployment" was needed.
She urged the government to abandon a "one-size fits all approach" to economic support, calling for measures "more focused" on individual sectors.
She added that spending to improve prisons and courts had been promised "quite some time ago," adding: "What the prime minister is talking about appears to be mainly spending that's already been committed to".
Liberal Democrat education spokeswoman and party leadership contender Layla Moran said Mr Johnson's plans looked like "a rehash of manifesto pledges" and accused the government of "running out of ideas".
Federation of Small Businesses (FSB) national chairman Mike Cherry said the announcement was "encouraging" but said it was important that small businesses were not "locked out of the ambition to build... because of cumbersome public sector procurement rules".
And British Chamber of Commerce director-general Adam Marshall said the government's plans had to "take shape on the ground swiftly to give a real confidence boost to businesses and communities".
