Hello and welcome to NewsHour from the BBC World Service.

Coming to you live from London, I'm Paul Henley.

Coming up later on the programme, a preliminary investigation is released on last month's Air India Crash,

which killed 260 people shortly after take off from Armidabad,

will have reaction from the granddaughter of one of the victims.

For me, I can't sort of stop thinking about what my grandma's final moments must have looked like.

And, yeah, it doesn't help the grieving process.

But first, President Trump has made another tariff threat.

Does he mean it this time?

Mr. Trump's published letters saying he intends to impose 30% tariffs on goods imported to the US from the EU and from Mexico,

starting from the 1st of August, blaming both the US trade deficit with the EU and Mexico's role in the flow of illicit drugs into the US, especially fentanyl.

The EU has been a frequent target of President Trump's criticism.

Here he is speaking on a live stream to the World Economic Forum back in January.

From the standpoint of America, the EU treats us very, very unfairly, very badly.

They have a large tax that we know about and of our tax, and it's a very

substantial one. Justin Wolfers is a professor of economics and public policy at the University

of Michigan in the US. What did he make of this announcement?

It sounds like the president's view is that the only real problem with Trumpism is we didn't

Day tariffs. In the case of the EU and Canada, particularly Brazil, far worse.
