Sawt Falasteen - UK's Labour govt prepares to unveil its first budget

The highly-anticipated fiscal update -- the first under the centre-left government after 14 years of Conservative rule -- is crucial to Starmer's mission of firing up Britain's sluggish economy.

The fresh government has promised a "decade of national renewal" as it pledges to protect living standards, fix public services and spur investment.

But it will have to square such promises with the reality of public finances strained by surging debt over recent years caused largely by the Covid pandemic, according to analysts.

Finance minister Rachel Reeves, who will present the budget to parliament, has promised "iron discipline" over public finances.

Below AFP looks in more detail at what to expect from her tax and spend plans.

- Fiscal rule changes -

Reeves on Thursday announced a shakeup of Britain's fiscal rules, giving the government room to borrow billions more to fund investment in publicly-funded projects.

"We need to invest more to grow our economy... but we'll only be able to do that if we change the way that we measure debt," she told the BBC.

It is expected that she will use a wider measure of debt that takes into account the future returns on investment.

Analysts estimate that the change could free up to £50 billion ($65 billion) in extra fiscal headroom.

- Tax rises -

The government has pledged to claw back what it says is a £22-billion black hole in public finances inherited from the previous Tory government.

"Alongside tough decisions on spending and welfare... taxes will need to rise," Reeves wrote in the Financial Times on Thursday.

She added that her new fiscal rules would ensure day-to-day spending is matched by revenues.

Labour has pledged not to hike taxes on "working people", which would appear to rule out raising income tax.

"The tax rises that are most likely at this budget include an increase to capital gains tax," said Kathleen Brooks, research director at trader group XTB, adding that the government may hike inheritance levies.

There are reports also that banks could face a windfall tax.

- Growth forecasts -

Alongside the budget, government fiscal watchdog the Office for Budget Responsibility (OBR) will provide revised forecasts on Britain's economic growth.

The International Monetary Fund (IMF) recently forecast that the UK economy would grow 1.1 percent this year, up from 0.7 percent.

The OBR will also update 2025 economic growth forecasts and assess future UK debt levels.

The UK faces the highest levels of state debt since the 1960s, with the figure nearing 100 percent of British gross domestic product, according to official data.

In a positive sign for the UK economy, inflation has fallen below the Bank of England's two-percent target, triggering cuts to interest rates.

- Pre-budget policies -

Labour has already announced several key economic policies since winning the election by a landslide at the start of July, including moves to improve relations with the European Union following Brexit.

Starmer has attended international summits and travelled to European capitals seeking to repair relations with allies that were damaged by Britain's EU departure.

The government has also launched a flagship green-energy plan, with the creation of a publicly-owned body to invest in offshore wind, tidal power and nuclear power.

Plans to fully nationalise Britain's railways and create a new national wealth fund to boost private investment for new infrastructure projects have also been unveiled.

While the government has faced widespread criticism over scrapping a winter fuel-benefit scheme for millions of pensioners, it has won plaudits from unions for agreeing new pay deals for public and private-sector staff, notably junior doctors, that have ended crippling strikes.
