Now this is the kind of change we believe in:

The US has lifted a 22-year immigration ban which has stopped anyone with HIV/Aids from entering the country.

President Obama said the ban was not compatible with US plans to be a leader in the fight against the disease.

The new rules come into force on Monday and the US plans to host a bi-annual global HIV/Aids summit for the first time in 2012.

The ban was imposed at the height of a global panic about the disease at the end of the 1980s.
