Write a short, clear, factual news headline based on this article: Bisphenols and phthalates were found in popular headphone sets that can interfere with hormone-regulating systems.

But, inevitably, most of the focus likely to be on how Starmer responds to the latest provocations from Donald Trump.

To recap: last weekend Trump was dismissing the UK’s stance saying that the US did not need Britain’s support in the Gulf anyway because “we don’t need people that join wars after we’ve already won”. This weekend he was asking the UK, and other countries, to send warships to help keep the strait of Hormuz open. The government has indicated that it won’t deploy warships, but it may send minesweeping drones. Here are some of today’s headlines.

The full Guardian story is here.

After briefly sounding solicitous, Trump is now back in threat mode. In a brief interview with the Financial Times he implied that, if countries like the UK did not deploy warships to protect oil tankers going through the strait of Hormuz, he might pull the plug on Nato. He said:

It’s only appropriate that people who are the beneficiaries of the Strait will help to make sure that nothing bad happens there …

If there’s no response or if it’s a negative response I think it will be very bad for the future of Nato.

We will hear what Starmer has to say about this later, but we have already had a response from Pat McFadden, the work and pensions secretary, who has been on the morning interview round. Speaking on Sky News, McFadden downplayed the threat, arguing that the US-UK alliance was strong enough to “outlast” any problems caused by Trump’s rhetoric. Asked to comment on the quote, he said:

That’s the president right there. The quote that you’ve just given has summed him up.

It’s a very transactional presidency and our job is to navigate this, to always remember that the friendship between the United States and the United Kingdom runs very deep.

It’s a good relationship. It’s enduring and I think it will outlast all the personalities involved.

We will cover the press conference in detail, but we won’t just be focusing on Iran today; there is other politics around too. Here is the agenda for the day.

I can’t read all the messages BTL, but if you put “Andrew” in a message aimed at me, I am more likely to see it because I search for posts containing that word.

If you want to flag something up urgently, it is best to use social media. You can reach me on Bluesky at @andrewsparrowgdn.bsky.social. The Guardian has given up posting from its official accounts on X, but individual Guardian journalists are there, I still have my account, and if you message me there at @AndrewSparrow, I will see it and respond if necessary.

I find it very helpful when readers point out mistakes, even minor typos. No error is too small to correct. And I find your questions very interesting too. I can’t promise to reply to them all, but I will try to reply to as many as I can, either BTL or sometimes in the blog.
