The Organisation for Economic Co-operation and Development upgraded its GDP growth forecast for 2023 from zero in June to 0.3 per cent.
But this was still behind the 0.6 per cent predicted rise for the eurozone, where there were stark divisions with Germany’s economy set to shrink by 0.2 per cent, France to grow by one per cent, and Spain by 2.3 per cent.
The UK’s economy was forecast to grow by 0.8 per cent next year, still below the 1.1 per cent for the Eurozone.
However, looking back to 2022, the UK had the biggest growth spurt of 4.1 per cent of leading wealthy nations, after its sharp Covid slump.
Last year, the UK saw inflation average at 9.1 per cent over the year, with a peak of 11.1 per cent.
On Tuesday, the OECD said it expects UK inflation of 7.2 per cent for 2023, increasing its previous forecast of 6.9 per cent from June.
This would be the fastest rate across the G7 (US, UK, Canada, Japan, France, Germany and Italy) and third fastest across the G20.
High inflation has hit the budgets of millions of people across Britain in the cost-of-living crisis.
Chancellor Jeremy Hunt said: “Today the OECD have set out a challenging global picture, but it is good news that they expect UK inflation to drop below three per cent next year.
“It is only by halving inflation that we can deliver higher growth and living standards. We were among the fastest in the G7 to recover from the pandemic, and the IMF have said we will grow faster than Germany, France, and Italy in the long term.”
But Shadow Treasury minister Darren Jones said: “Businesses and workers across the country deserve better, which is why Labour has a plan for the economy to boost growth, increase wages and bring down bills so working people are better off.”
Liberal Democrat Treasury spokesperson Sarah Olney added: "This damning report shows that under the Conservatives, the UK economy is stuck in the slow lane.
“We’ve had zero apology from Liz Truss for trashing the economy, and now zero plan from Rishi Sunak to fix it.”
