Donald Trump has asked the US supreme court to overturn a lower court decision that most of his sweeping trade tariffs were illegal.

The US president filed a petition late on Wednesday to ask for a review of last week’s federal appeals court ruling in Washington DC, which centred on his “liberation day” border taxes introduced on 2 April, which imposed levies of between 10% and 50% on most US imports, sending shock waves through global trade and markets.
