The UK Finance Minister, Rachel Reeves, promises the most "pro-growth, pro-business" government the country has ever had.

• Reeves stated via remote interview with CNBC's Steve Sedgwick that this Treasury will be the most pro-growth and pro-business in the country's history.
• Rachel Reeves, the U.K.'s Chancellor, addressed a G20 meeting of finance ministers in Rio de Janeiro, Brazil.
• On Monday, Reeves will disclose a £20 billion ($25.7 billion) deficit in the Treasury's audit results.

The new Labour government, led by Finance Minister Rachel Reeves, will be the most growth-oriented and business-friendly in the UK, according to a statement made on Friday.

According to Reeves, improving the living standards of ordinary Britons and increasing investment in public services can only be achieved through wealth creation.

Reeves stated via remote interview with CNBC's Steve Sedgwick that this Treasury will be the most pro-growth and pro-business in the country's history.

She stated that she would collaborate with businesses to maximize wealth creation and attract investment to the U.K. economy.

Reeves, who has been in post for three weeks since Labour's landslide victory in the U.K.'s July 4 general election, is currently in Rio de Janeiro, Brazil, attending a meeting of G20 finance ministers.

The chancellor stated that she has already met with business leaders interested in conducting business in the U.K. She, however, recognized the need for greater clarity on taxation.

On Monday, Reeves will disclose a £20 billion ($25.7 billion) deficit in the Treasury's audit results.

The announcement of the first major fiscal event of the new government, which could lead to a tax-rising Autumn Budget, will be made on Monday, along with the date of the financial plan.

Reeves declined to provide specifics on tax details, stating that budget issues should be addressed. However, she emphasized the importance of a competitive tax system for Britain.

"I want taxes to be as low as possible, but I won't make promises I can't keep and without specifying where the funds will come from. My government's top priority is to boost the economy by attracting wealth creators to Britain," she stated.

"To achieve higher growth and greater prosperity, we cannot rely solely on taxing and spending. Instead, we must focus on attracting business investment."

Although Reeves has previously ruled out increasing income tax, national insurance, VAT, or corporation tax as the primary sources of government revenue, the chancellor must strike a delicate balance between fulfilling her party's promises to increase national investment and public sector pay.

On Wednesday, Keir Starmer, the Prime Minister, stated that there would be difficult financial choices in the future, as his government is facing a more severe crisis than initially anticipated due to the 14-year Conservative rule.

The leader on the left has pledged to be tough on public spending until the country's finances are balanced. On Tuesday, he suspended seven party members who opposed him on a plan to eliminate the two-child benefits spending cap.

The King's Speech last week reiterated Labour's commitment to restoring economic growth as a fundamental mission, as the country strives to overcome its cost of living crisis.

The government has previously announced economic measures such as nationalizing rail operators, establishing a publicly-owned clean power company, increasing investment in public services, and creating new homes.

The new finance minister's first international meeting was at the G20, where he expressed his desire to "reset" some of Britain's relationships with its counterparts.

Starmer's government is seeking to distance itself from the former U.K. leadership, as he echoes similar remarks made at the European Political Community summit last week.
