A 26-year-old biker who died in a crash in the Scottish Borders on Saturday has been named by police.

She began Thursday's morning press briefing by referring to new figures from the US Customs and Border Protection agency which show seizures of fentanyl have dropped to 263 kilos, their lowest levels in 3 years. It represents a 75% drop in the last six months of her presidency.When tariffs were avoided in February, Sheinbaum agreed to deploy 10,000 troops to the US-Mexico border.

Her administration has also extradited (although they prefer the word "expelled")to the US to face trial on charges from murder to money laundering, including a top drug lord, Rafael Caro Quintero, who has been wanted by the US authorities since the mid-1980s.Those may well have been the measures Trump was referring to when he said the two countries were "working hard, together" on border security.

Furthermore, she has often thrown the ball back in the US president's direction.Where do the guns which arm the cartels come from, she asks rhetorically, openly calling for the US to do more to curb the flow of weapons south and tackle its demand for illegal drugs. The drugs may come from Latin America, she points out, but the market for their consumption is overwhelmingly in the US.

Even when the Trump administration recently designated six Mexican cartels as "foreign terrorist organisations", it seemed to strengthen her hand.

That's because her administration is currently embroiled in a legal battle with US gun manufacturers over negligence. If US weapons-makers have allowed their products to reach terrorists rather than mere criminals, Mexico could expand its lawsuit, she said, to include a new charge of "complicity" with terror groups.It remains to be seen whether Canadians can have a strong trading relationship with the United States going forward, he added.

Carney has switched his campaign plans ahead of next month's general election to confront the latest import duties.The US has already partially imposed a blanket 25% tariff on Canadian goods, along with a 25% duty on all aluminium and steel imports. Canada has so far retaliated with about C$60bn ($42bn; £32bn) of tariffs on US goods.

The new car tariffs will come into effect on 2 April, with charges on businesses importing vehicles starting the next day, the White House said. Taxes on parts are set to start in May or later.Early on Thursday morning, Trump warned Canada and the EU against joining forces versus the US in the trade war.
