LONDON - British retail sales surged by much more than expected in November, boosted by Black Friday promotions, although the longer-term picture remains weak ahead of Brexit in little more than three months' time.
Retail sales volumes in November, including the Black Friday sales period, jumped by 1.4 percent from October, surpassing all forecasts in a Reuters poll of economists that had pointed to a 0.3 percent gain.
But looking at the three months to November as a whole, which smooths out some monthly volatility, sales were up just 0.4 percent compared with the previous period -- the smallest increase since April.
The November sales surge reported by the Office for National Statistics (ONS) on Thursday contrasted with statements from some major retailers that showed a disappointing Black Friday.
An ONS statistician said the changing nature of Black Friday sales promotions posed a challenge for the process of adjusting for seasonal variations.
Online fashion store ASOS issued a profit warning on Monday as its November trading fell short of expectations, while the owner of the Primark clothing retailer said the market was "challenging" last month.
The ONS said household goods sales leapt by 5.3 percent on the month in November, the biggest increase since the end of 2013.
Online sales as a proportion of all retailing exceeded 20 percent for the first time, the ONS said.
Thursday's ONS numbers will not influence the Bank of England's policy announcement due at 1200 GMT because the central bank's interest rate-setters have already concluded their December meeting.
They did not see the ONS retail sales report in advance.
