Confidence in the UK's economy is beginning to rise, with vacancies reaching their highest level since 2008.

Figures from the Office of National Statistics showed that 503,000 jobs were advertised between February and April 2013, which was the highest number since October 2008.

The UK's economy has been buoyed by strong figures from the service sector, in particular from restaurants, hotels and the leisure industry.

The Confederation of British Industry's quarterly survey found that the consumer services sector had experienced its biggest rise in optimism for six years, with the reading now standing at its highest level since 2009.

The data showed a marked increase in confidence between February and April, and profit expectations for the next quarter were also at their highest level since 2007.

The services sector is the driving force of the UK's economy, representing around three quarters of it.

Stephen Gifford, director of economics at the CBI, said: "There appears to be a sense of growing confidence in the service sector."

"We've seen some turnaround in activity this quarter, and a more positive outlook for the next. What's promising is that consumer services have seen growth in activity, and expect this to continue pointing to a greater willingness from people to go out and spend."

This news follows the announcement earlier in the month that the Bank of England would lower its inflation forecast and improve its growth forecast for the rest of the year.
