The US Supreme Court has struck down President Donald Trump's executive order limiting birthright citizenship

In a 6-3 decision, the justices upheld a 150-year-old precedent giving automatic American citizenship to babies born in the US

Trump earlier issued an order to end automatic citizenship for babies born to parents who are in the country illegally or on temporary visas

Opponents say the order violated the US Constitution's 14th Amendment, which says that people "born or naturalised" in the country are citizens - how it works

The court has also ruled that states can ban transgender athletes from women's sports in schools and struck down a ban on how campaign spending is coordinated
