The UK economy grew by 0.1% during the three months of 2018, down from 0.4% in the previous quarter, the Office for National Statistics (ONS) said.
The weak growth was driven by a sharp fall in construction output and a sluggish manufacturing sector, while growth in services also slowed.
The ONS said the extreme weather of February and March had had a “relatively small” impact.

“While the snow had some impact on the economy, particularly in construction and some areas of retail, its overall effect was limited with the bad weather actually boosting energy supply and online sales.”
