The United States Supreme Court has upheld Barack Obama's landmark overhaul of the country's healthcare system, bolstering his chances in a close re-election race this November.

The health care bill has been strongly opposed by the Republicans, with Mitt Romney saying he will repeal the law if he is elected president.

However, health care workers and underprivileged citizens say the move will help many who had been left out in the cold, and that the new law will help them get the care they needed.
