This latest twist in the Trump trade tariff drama has many people asking what it means for the UK's deal with the US.
The answer is actually not as much as you might think.
For a start, the tariffs that the US court has ruled illegal do not include those on cars, which make up the bulk of what the UK exports to the US, and steel and aluminium, which are the other UK industries most affected.
UK exports of cars are currently attracting 27.5% tariffs while steel and aluminium are hit with 25% tariffs - the same as every other country. Wednesday's ruling has not changed that.
