Manufacturing activity in the UK inched higher in May after hitting a seven-month low in April, but strong domestic demand was largely offset by weak exports.
The Markit/CIPS manufacturing Purchasing Managers' Index (PMI) rose to 52.0 in May from a downwardly revised 51.8 in April, a weaker increase than the rise to 52.5 forecast by a Reuters poll of analysts.
"Expectations of a broad rebound in UK economic growth during the second quarter of the year are called into question by these readings," Markit senior economist Rob Dobson said.
"Manufacturing looks on course to act as a minor drag on the economy, as the sector is hit by the combination of the strong pound and weak business investment."
Hiring was the slowest in more than two years, suggesting the boom in job creation that Britain has enjoyed since mid-2013 may be starting to tail off.
British factory output rose just 0.1 percent in the first three months of 2015, official figures showed on Thursday, and earlier on Monday an industry body cut its growth forecast for 2015 as a whole, citing knock-on effects from weakness in the oil and gas sector.
The downbeat news on manufacturing contrasts with a more upbeat message in other sectors of the economy, and on Sunday the Confederation of British Industry said the private sector as a whole was enjoying its fastest growth for a year.
The PMI's output growth component edged downwards to its lowest since September 2014.
Markit, which compiles the survey, said consumer goods was the best performing area, and investment also strengthened modestly. Orders growth was little changed from April, while export demand was stable after a fall the month before.
Sterling hit its highest level on a trade-weighted basis since mid-2008 in May.
Dobson said manufacturers were facing a "double-whammy" from currency strength as it encouraged consumers to buy imported goods instead, something which also showed up in Thursday's weak first-quarter GDP data.
