by imposing import taxes on most of the US's trading partners.

Judge Rudolph Contreras found the duties went beyond the president's authority, but his ruling only applied to a toy company in the case.Trump trade adviser Peter Navarro told reporters on Thursday: "You can assume that even if we lose [in court], we will do it [tariffs] another way."

No court has struck down tariffs on cars, steel and aluminium that Trump imposed citing national-security concerns under Section 232 of the Trade Expansion Act of 1962.He could expand import taxes under that law to other sectors such as semiconductors and lumber (processed wood known as timber in the UK).The president could also invoke Section 301 of the Trade Act of 1974, which he invoked for his first-term tariffs on China.

A separate 1930 trade law, Section 338 of the Trade Act, which has not been used for decades, allows the president to impose tariffs of up to 50% on imports from countries that "discriminate" against the US.But the White House is also expected to press forward in challenging the court rulings. The matter is widely expected to end up at the Supreme Court.

Lawyer Ilya Somin, who helped work on the case brought by businesses before the trade court, said he was "guardedly optimistic" the ruling would ultimately be upheld on appeal.

He noted that the trade court order came from justices appointed by both Democratic and Republican presidents, including one by Trump himself.A migraine - which can last days - is very different to a headache, which tend to be short-lived and can be treated more easily with painkillers like paracetamol. Migraines can cause head pain, neck pain, numbness, blurred vision, and even affect speech and movement.

Skulls dating back to 3,000 BC show ancient Egyptians even had trouble with migraines - but despite that long history, their exact cause is still unknown.It's thought pain receptors in the blood vessels and nerve tissue around the brain misfire - sending incorrect signals that something is wrong. But we don't know why some people have an oversensitive nervous system - and why it reacts to some things and not others.

Experts say there's not enough research into why only some people - around one in seven - are affected, or what can actually help.Dr Kay Kennis, a trustee for the Migraine Trust and a GP who specialises in migraines, says while there are elements of the McMigraine meal that can help stave off an attack, these aren't innate to "a McDonald's".
