Chancellor Jeremy Hunt will today set out his plan to boost growth, as criticism mounts over the UK Government's plan for the economy.
In his speech in London, Mr Hunt will outline the opportunities in what he called "the growth sectors which will define this century".
He will also pledge to build on "the freedoms which Brexit provides".
But it comes in a week the government has faced accusations that it has no long-term plan for growth.
On Monday, the CBI business group warned the UK is lagging behind rivals on green growth.
The next day, insolvency firm Begbies Traynor said the number of firms on the brink of going bust jumped by more than a third at the end of last year.
No strategy
And, on Thursday, car firms warned the UK has not got a strategy to attract manufacturers.
Speaking at Bloomberg's Headquarters in London, Mr Hunt will set out how the government plans to achieve growth in multiple sectors across the UK.
The BBC says the speech will focus on key growth industries such as digital technology, green industries, life sciences, advanced manufacturing and creative industries.
He will also set out a long-term plan to tackle poor productivity.
"It is a plan necessitated, energised and made possible by Brexit which will succeed if it becomes a catalyst for the bold choices we need to take," he will say.
Looking at the wider picture, Mr Hunt will say that "declinism about Britain" was wrong before and is wrong today, adding that some downbeat forecasts "do not reflect the whole picture".
He will praise what he calls "British genius and British hard work", and promise to turn that into prosperity in the long term.
Reverse
It is the chancellor's first big economic speech since he took office in October, outside of the Autumn Statement and his speech to reverse most of Liz Truss's mini-Budget.
Many will see this latest speech as an attempt to respond to criticism that the government has no long-term plan for growth, in the face of the global economic shift.
- British stocks have suffered a "breathtaking" fall from grace and are no longer seen as must-own assets, a powerful group of international investors has claimed.
The Investor Forum, which represents top fund managers such as Blackrock, Aviva, UBS and Norway's oil fund, said corporate boards, investors and regulators needed to do more to attract investment into the UK in the face of more competition than ever for capital.
Andy Griffiths, executive director of the Investor Forum, told the Telegraph: "The declining relevance of UK equity markets over the last 25 years has been breathtaking.
"It is crucial that the focus of any reform recognises the global nature of financing and seeks to create an environment in which UK listed companies can once again thrive.
"We cannot simply hope for a better outcome - practical steps are needed from companies, investors and regulators if we are to create a vibrant marketplace which can attract international capital."
Without urgent reforms to make listing in Britain and investing in UK-listed companies more attractive, the country's markets will continue to diminish in importance, the forum warned.
