GROWTH of Scotland's private sector economy accelerated to its fastest pace in a year in April, and was ahead of the UK average, a survey has revealed.

The latest Purchasing Managers' Index (PMI) report, published by Bank of Scotland today, also shows a return to growth in the manufacturing sector north of the Border in April, following nine consecutive months of contraction.

However, the survey signals only very modest growth in the manufacturing sector last month.

Growth in Scotland's dominant services sector meanwhile accelerated sharply between March and April.

The PMI report will provide some relief at a time when the economy continues to face significant headwinds from the Coalition Government's austerity measures and difficulties in the eurozone.

Donald MacRae, chief economist at Bank of Scotland, expressed hopes on the back of the latest survey that Scotland was "now beginning a more robust recovery".

The headline Bank of Scotland PMI rose from 51.1 in March to 53.1 in April on a seasonally-adjusted basis, climbing further above the level of 50 which is deemed to separate expansion from contraction to signal an acceleration in growth of output.

The April PMI reading for Scotland is ahead of the UK average of 52.4, signalling slightly faster growth north of the Border. Scotland's PMI output index had been slightly below the UK average of 51.4 in March.

The latest PMI report shows the pace of growth in employment in the Scottish private sector accelerated for the third time in four months in April, to reach its fastest pace since last July.

Both the Scottish services and manufacturing sectors recorded a rise in staffing in April.

But the latest survey, compiled by financial information firm Markit, signals that Scottish manufacturers' new export orders were unchanged between March and April.

The PMI Scotland report reading for Scottish manufacturers' new export orders has been at, or close to, the neutral 50 mark since December 2012, signalling a sustained flat trend in new demand for Scottish goods overseas.

The pace of total incoming new business accelerated in both the manufacturing and services sectors north of the Border in April.

New business inflows in Scotland's private sector have increased in every month since last December.

Mr MacRae said: "April's PMI climbed to a 12-month high, signalling growth in the private sector of the Scottish economy at the start of the second quarter of the year.

"Both business activity and employment grew in the manufacturing and services sectors while the volume of new business rose for the fifth month in a row."

Mr MacRae, however, highlighted the lack of growth in exports for Scottish manufacturers.

Referring to the growth of new business in the Scottish private sector economy, he said: "Demand growth was largely UK-based, with the level of new export orders showing a flat trend for the last five months."

He added: "These results suggest the Scottish economy is now beginning a more robust recovery."

Data published last month by the Scottish Government showed the economy north of the Border grew by 0.5% in the fourth quarter of last year, as renewable energy output rose and the service sector grew.

News of the strong quarter-on-quarter rise in Scottish gross domestic product came as a surprise, given a 0.3% fall in UK-wide GDP in the final three months of last year.

The data showed services output in Scotland grew by 0.3% quarter-on-quarter in the final three months of 2012 in spite of a 4.2% drop in activity in the financial and insurance category. And there was an 8.8% quarter-on-quarter leap in electricity and gas supply in Scotland in the final three months of 2012, much greater than a corresponding 2.2% rise UK-wide.
