Unemployment in the eurozone hit a record high at the end of last year, the Eurostat agency has said.

The jobless rate in the 17 countries that use the single currency was 10.4% in December, unchanged from November's figure which was revised up from 10.3%, reports BBC.

Some 16.5 million people were out of work in the eurozone in December, up 751,000 on the year before.

The highest unemployment rate remains in Spain (22.9%), while the lowest is in Austria (4.1%).

Unemployment has been rising throughout 2011, as the debt crisis in the region has continued. In December 2010, the unemployment rate in the euro area was 10%.

Guillaume Menuet, economist at Citigroup, said he expected the number of people out of work to increase throughout 2012.

"If you think about the direction of employment expectations that you see across various business surveys, the outlook for employment doesn't look particularly enticing, simply because the uncertainty is very high.

"In many cases you find firms continuing to delay investment projects. For those that are still making profits, hiring is being frozen, and for those which are under pressure to hit results or losing money, job losses are becoming the only solution that they have," he said.

In the 27 EU countries, the unemployment rate was 9.9% in December, with 23.8 million people out of work. November's figure was also revised up from 9.8% to 9.9%.
