Quoting from my own manifesto

From slides 14 to 16 of this:

2009-10 figures from HM Treasury:
* Tax and other revenues: £478 billion (Excel)
* Other income, adjustments approx: £60 billion
Total income £538 billion

* Cash welfare spending: £218 billion
* Public sector salaries and pensions: £169 billion
* Money paid to private sector businesses: £281 billion.
* Interest payments: £31 billion
Total spending: £699 billion

= Deficit spending approx: £161 billion

Deficits could be eliminated by any one of the following:
* Increasing tax revenues by 33%
* Reducing public sector employment costs by 95%
* Reducing welfare and pensions by 73%
* Reducing spending on private sector procurement by 43%

The best way of eliminating the deficit would appear to be as follows:
* Keep tax revenues and welfare/pensions spending constant, and
* Reduce public sector employment costs and spending on private sector procurement by one-third.

Said is said.
