The US Supreme Court has voted in support of the Affordable Care Act, also known as Obamacare, giving a massive boost to the president whose name has long been attached to the law.

Justices voted 6-3 to uphold Obamacare and keeping subsidies that help some 6.4 million people in 34 states afford health care.

The case in front of the high court centered on the argument that people in states without their own health insurance exchange were ineligible to receive assistance to pay for health care coverage.

Thursday's decision ends a long run of legal challenges for Obamacare, prompting President Obama to say the law is here to stay - at least as long as he is president.

"After more than 50 votes in Congress to repeal or weaken this law, after a presidential election based in part on preserving or repealing this law, after multiple challenges to this law before the Supreme Court, the Affordable Care Act is here to stay," Mr Obama said.

In trumpeting some of the highlights of what may be the defining policy of his presidency, Mr Obama said more than 16 million people who were uninsured before Obamacare now have health insurance.

The president also said that the US rate of the uninsured has never been lower since such statistics have been recorded and that, since the law was passed in 2010, the US has seen the slowest growth in health care cost in 50 years.

"Five years in, this is no longer about a law," Mr Obama said shortly after the decision was announced. "This is health care in America."
