President Barack Obama today made the most contentious move of his young administration with an order, overturning a ban on federal funds to foreign family planning organisations that either offer abortions or provide information or counselling about abortion. The rule change continues the dismantling of George Bush's conservative policies. It is likely to encounter fierce criticism from the still robust anti-abortion movement.

It will allow US aid, usually through the US agency for international development, to flow to HIV/Aids clinics, birth-control providers and other organisations that advocate or provide counselling about abortion across the world. It is known as the "global gag rule" because it denies US taxpayer dollars to clinics that even mention abortion to women with unplanned pregnancies.

The rule was signed by President Ronald Reagan in 1984, overturned by Bill Clinton in 1993, and reinstated by Bush. Critics of the rule say it deprives the world's poor women of desperately needed medical care, while proponents say US tax dollars should not promote abortion.
