In December, 18,000 people received notice, compared to 2,000 in December 2007.
By the end of the 2008, 188,000 people were registered with the agency as being unemployed, an increase of 27,000, or 0.5 percentage points, on the same period the previous year.
The number of people working with various forms of supported employment totalled 77,000, a drop of 16,000 compared to the same period in 2007.
