Dear ____,

Tax dodging costs the UK £100 billion a year. That's enough to double funding for the NHS. Developing countries lose an estimated £250 billion every year as a direct result of corporate tax dodging - money which could be used to reach the UN's Millennium Development Goals several times over.

The UK plays a major role in tax dodging, with many of the world's tax havens British dependencies such as Jersey or overseas territories such as the Cayman Islands. The City of London acts as the financial nerve centre for these tax havens and supports an army of pinstriped lawyers and accountants devoted to helping companies dodge tax.

Companies should pay their fair share of tax not only here but in the developing world. Taxes collected should be used to help fund vital public services such as healthcare, education and housing in developing countries as well as in the UK.

As part of War on Want's campaign for tax justice, I ask you to write to the Prime Minister urging him to take firm action to end tax dodging by:

• putting a moratorium on staff cutbacks and tax office closures in HM Revenue & Customs
• abolishing UK tax havens
• working with other countries to eradicate trade mispricing and promote transparency through 'country by country' reporting by companies
• prosecuting corporate executives, lawyers and accountants for profit laundering and tax dodging
