What does the budget deficit really look like?

An interesting graph that I noticed on Paul Krugmans blog:



As can be seen - the graph segments the deficit across a range of different factors. I wonder what it would look like if you did a similar analysis for the UK and included

• Cyclical effects due to the downturn, 
• Tax revenue changes due to taxation changes (eg. corporation tax changes)
• Lower tax revenues/increased welfare spending due to government economic policy
• The structural deficit
