Millions of women across the US could soon lose their legal right to abortion, according to a leaked Supreme Court document.

The document, published by Politico, suggests the country's top court is poised to overturn the 1973 decision that legalised abortion nationwide.

If the Supreme Court strikes down the Roe v Wade ruling, then abortion could be banned in almost half of US states.

Its justices are expected to issue a ruling in late June or early July.
