Britain's economy grew faster than previously thought at the end of last year but the current account deficit hit its highest level since records began, according to official figures.
The Office for National Statistics today revised up its figure for gross domestic product (GDP) to 0.6% in the fourth quarter.
This was up from the previous estimate of 0.5%.
The revision was triggered by a stronger performance from the dominant services sector and a smaller contraction within industrial production.
The UK current account deficit widened to £32.7 billion in the fourth quarter, compared to £20.1 billion in the third, causing the deficit as a share of national income to reach 7% - the highest deficit recorded since 1955.
The economy also fared better for the whole of 2015 than previously recorded, with GDP being revised up to 2.3% from 2.2%, the ONS said.
British Chancellor George Osborne said the upward revisions to GDP meant Britain remained "one of the fastest-growing major advanced economies".
"However, the UK is not immune to risks in the global economy as slowing global growth weighs on our outlook," he stated.
"Today's figures expose the real danger of economic uncertainty and shows that now is precisely not the time to put our economic security at risk by leaving the EU," he added.
The Chancellor had warned in his Budget earlier this mont that the UK economy still faced "dangerous cocktail risks" as a slowdown in China, increased market volatility and low commodities prices cause dark clouds to gather over the global economy.
The ONS said the UK economy was also stronger in the first quarter of last year, revising it up to 0.5% from 0.4%, while the second quarter and third quarters remained at 0.6% and 0.4% respectively.
The level of real household disposable income decreased by 0.6% in the fourth quarter, down from a 1.6% increase in the third quarter.
ONS chief economist Joe Grice said that the latest GDP data shows the UK economy ended 2015 a little more strongly than previously thought.
"But the figures also show a fall in household incomes, with the saving ratio reaching a record low and a record current account deficit," he added.
Britain's powerhouse services sector - which counts for more than three-quarters of the economy - grew by 0.2% between December and January, down slightly on growth of 0.3% between November and December last year.
