London - Britain's manufacturing sector shrank for a second consecutive month in March, a survey showed on Tuesday, leaving the country's more resilient services sector as the best hope of avoiding a new recession.
The Markit/CIPS manufacturing purchasing managers' index came in at 48.3, only slightly above February's shock reading of 47.9, and a touch weaker than the consensus forecast.
The output component of the survey fell in March at its fastest pace since October.
The survey suggests manufacturing exerted an even bigger drag on growth between January and March than it did in the fourth quarter of 2012, when it accounted for a third of the economy's 0.3% contraction.
"The onus is now on the far larger service sector to prevent the UK from slipping into a triple-dip recession," said Rob Dobson, senior economist at Markit.
Official GDP data for the first quarter won't be released until April 25 but the evidence so far suggests a strong risk that Britain will record a second consecutive quarter of contraction - the technical definition of recession.
A third recession in less than five years would be an embarrassment for the government which is sticking to tough austerity measures despite faltering growth at home and abroad.
Despite the weakness in the economy, the Bank of England is not expected to take new stimulus measures when it meets on Wednesday and Thursday, although more action is widely expected before the end of the year.
The Markit report blamed the poor performance of manufacturing in March on tough market conditions, subdued client confidence and ongoing bad weather.
New orders from abroad contracted for the 15th month running in March. The survey blamed the fall on weak demand from Europe and strong competition in US and South Asian markets.
In further bad news for UK policymakers, there were also signs that inflation pressures were picking up. Output prices rose at the fastest pace in three months while input prices picked up sharply, driven by the weakness of sterling and higher energy and food costs.
Manufacturing accounts for around a fifth of British economic output. Surveys of the construction and service sectors for March are due to be released on Wednesday and Thursday respectively.
There have been signs that the services sector is faring better than manufacturing. It grew at its fastest pace in five months in February, according to Markit and official data showed it notched up its best performance in January for five months.
