Hello and welcome to NewsHour from the BBC World Service.

We're coming to you live from London.

I'm Leila Naffey.

Coming up on the programme, far-right demonstrators marched through the French city of Lyon today, commemorating the death of one of their own.

The marchers were calling for justice for Conta Durant, who was beaten to death in an attack blamed on far-left militants.

We'll be hearing about the impact of his death on French

politics in about half an hour's time. But first, let us start in the US, where Donald Trump

has doubled down on his defiant response to the Supreme Court, which ruled yesterday that

most of the tariffs he announced last year were illegal. Having attacked the

justices as disloyal for voting that he had overstepped his authority by using emergency

legislation to impose the duties, President Trump said he would impose further global tariffs

at a rate of 10% using a different law. The Supreme Court's decision calls into question the trade deals signed by the US

with other countries on the basis of the original tariffs.

The French President Emmanuel Macron warned earlier today

against jumping to any conclusions.

We shouldn't go too fast either, because I note that President Trump, because I don't go too fast either, because I note that President Trump,

after a few hours, said he had revised the measures to introduce new tariffs.

But this time more limited and for everyone, so we will see.

We will look exactly at the consequences, what can be done and we will adapt.

Well, he was right to be cautious because later today, President Trump announced he'd in fact be raising his new tariffs to 15%, which he claimed was a level fully allowed and legally tested.

So where does this leave America's trading partners?
