Surging oil imports have propelled Britain's trade deficit with the rest of the world up faster than expected, to a new record for November.
Britain was a net importer of oil for the fifth month in a row
The trade gap in goods and services widened to £5.96bn ($10.45bn) from a deficit of £5.05bn in October, said the Office for National Statistics (ONS).
The November figure was more than £1bn higher than economists' forecasts.
The goods trade gap with non-EU countries also widened to £3.02bn in November from £2.28bn in October.
Economists had forecast a deficit of about £2.5bn.
In November, the UK was a net importer of oil for the fifth month running, the longest period since monthly records began in 1980.
"It's a shocking number, much worse than expectations," said Philip Shaw, economist at Investec.
"There are no significant implications for interest rates, but a widening of the UK's external balance will not be welcomed at the Bank of England."
