Britain's economy picked up in January after a weak December but the bigger picture remained one of growth stuck in low gear ahead of Brexit, official data showed. 

The UK's giant services industry more than reversed its fall in December.

Today's figures also show a turnaround in manufacturing with factories ramping up their stocks to hedge against the risk of a chaotic Brexit.

UK gross domestic product in January alone jumped by 0.5%, its biggest increase since December 2016, and more than reversing a 0.4% fall in December. 

Smoothing out the volatility, growth in the three months to January held at a sluggish 0.2%, the same pace as in the last three months of 2018. 

"Across the latest three months, growth remained weak with falls in manufacture of metal products, cars and construction, repair work all dampening economic growth," Rob Kent-Smith, an ONS statistician, said. 

The UK economy looks set for its weakest growth in 10 years in 2019, even if it pulls off a last-minute deal to smooth its exit from the European Union, according to Bank of England projections. 

With Brexit little more than two weeks away, Prime Minister Theresa May, armed with fresh reassurances from the EU, will try again today to overcome deep opposition in parliament to her plan to take Britain out of the bloc. 

If Britain leaves the EU without a deal, it could suffer a major shock to the economy. 

May has opened up the possibility of a delay to the scheduled March 29 Brexit date if her plan is defeated. 

Today's data showed that the UK services sector – which accounts for about 80% of Britain's private sector economy – grew by 0.3% in January after a 0.2% fall in December.

That left growth in the sector over the three months up a touch at 0.5%. 

Manufacturing output grew for the first time in seven months in January, up by a monthly 0.8% from December. 

An ONS official was unable to comment on whether the rise was linked to other signs of stockpiling by British manufacturers who are worried that a no-deal Brexit could cause port delays and hurt their production schedules. 

Over the three months to January, manufacturing output remained weak, down by 0.7%. 

Total industrial production also turned around on a monthly basis but fell over the three-month period. 

Construction, which accounts for about 6% of Britain's economy, reversed its fall in December to grow by 2.8% in January in monthly terms. 

There were also signs that the slowdown in the global economy was weighing on Britain too. 

The country's deficit in its trade in goods was the biggest since mid-2017 at £13.084 billion. 

Exports in the three months to January fell by 0.7% while imports were up 2% in volume terms.
