LONDON -- Official figures show that the British economy grew a bit more than previously thought last year.

The said 2017 growth was revised up to 1.8 per cent from 1.7 per cent previously. The economy has fared better than many thought after the Brexit vote in June 2016, with exporters in particular enjoying a lower pound.

Still, the 2017 growth performance was the worst since 2012 and doesn't change the underlying picture that the country's economy has slowed sharply since the Brexit vote in June 2016.

Brexit remains the biggest uncertainty surrounding the British economy. With a year to go until Britain officially leaves the EU, it remains unclear how the country will be trading with its main export market after Brexit.
