Britain's economy grew by just 0.3% in the second quarter, confirming fears of a marked slowdown as the country prepares to exit the European Union.
The rate of growth over the previous quarter represents a slight improvement on the 0.2% expansion posted in the first three months of 2017. The official data matched the expectations of economists, but gave little cause for optimism.
"The economy has experienced a notable slowdown in the first half of this year," the Office of National Statistics said in a statement.
The retail and film production sectors showed signs of improvement, but weakness in construction and manufacturing weighed on activity.
