The US Supreme Court has given the go-ahead to trump administration plans that severely limit the ability of migrants to claim asylum.

Under the rule, people arriving via a third country must claim asylum there first before arriving at the US border.

Legal challenges against it continue but the ruling means for now it can be enforced nationwide.

President Donald Trump tweeted that it was a “big United States Supreme Court win for the border on asylum!”

Curbing migration to the US has been a key goal of his presidency and forms a major part of his bid for re-election in 2020.

When it was unveiled this year in July it was almost immediately blocked from taking effect so the move is being seen as a victory for the trump administration in us media.
