Britain's industrial performance in June was marred by a poor showing from UK-based car manufacturers according to data from the Office for National Statistics.
The trade deficit widened during the month, but the rise in imports during June overshadowed a robust quarterly performance for export volumes.
Data on manufacturing and industrial production looked fairly solid at the headline level.
A 0.5% month-on-month increase in industrial production was more than welcome after May's 0.1% decline and beat analysts expectations of a 0.1% increase.
On an annualised basis, industrial production grew 0.3% compared with June 2016, a much better showing than May's 0.2% decline and expectations of a 0.1% fall.
The rise, however, was flattered by a 5% month-on-month increase in oil and gas output.
Manufacturers contributed little to the rise in production, with a flat reading for month-on-month growth in manufacturing output in June, which followed a 0.1% decline in May.
At the yearly level, manufacturing matched market expectations, rising 0.6% on last June, but was up from 0.3% in May.
"Car production was particularly weak. Moreover, the 0.1% fall in construction output was much weaker than the 1.8% rise that the ONS had pencilled in," said Paul Hollingsworth at Capital Economics.
James Smith, economist at ING, said: "This is particularly concerning when you consider the backdrop of a 13% post-Brexit fall in the pound and the significant improvement in global growth prospects."
Weakness in your domestic currency compared to that of your trading partners makes export more competitive as the exchange rate makes your goods worth more when export revenues are converted back into your currency.
"Whilst these developments appear to have boosted sentiment amongst manufacturing firms according to recent PMIs, we aren’t seeing this being translated into the official data," added Smith.
Although the trade deficit in goods and services expanded to £4.6bn in June from £2.5bn in May, quarterly data showed that exports were improving.
Quarterly growth in export volumes rose to 1.5% and was stronger than the 0.4% rise in exports.
"This suggest that net trade probably made a small positive contribution to gross domestic product growth in the second quarter, after exerting a 0.8 percentage point drag on growth in Q1," said Hollingsworth.
He added: "Looking ahead, surveys suggest that the manufacturing sector should gain some momentum in Q3, while export growth should pick up further."
The FTSE 100 had already been weak ahead of the data, but fell further following the release.
Britain's benchmark stock index was down 1.1% in late morning trade in London, with mining stocks showing some weakness and house builders were knocked by the construction data, and earlier figures showing slowing house price growth.
