Donald Trump has threatened sweeping new tariffs on Mexico, Canada and China on his first day in office.

The president-elect, who takes office on 20 January next year, said he would introduce a 25% tax on all products entering the country from Canada and Mexico.

Posting on his Truth Social platform he also threatened an additional 10% tariff on goods from China on top of any he might impose as one of his first executive orders.

What Trump’s tariffs could mean for UK, EU, China and the world

If implemented, the tariffs could raise prices for ordinary American consumers on everything from petrol to cars and agricultural products.

The US is the largest importer of goods worldwide and Mexico, China and Canada are its top three suppliers according to the country’s census data.

More than 83% of exports from Mexico went to the US in 2023 and 75% of Canadian exports go to the country.

“On January 20th, as one of my many first Executive Orders, I will sign all necessary documents to charge Mexico and Canada a 25% Tariff on ALL products coming into the United States, and its ridiculous Open Borders,” Mr Trump said.

He also spoke against an influx of illegal immigrants heading into the country.

While migrant arrests reached a record high during President Joe Biden’s administration, illegal crossings fell dramatically this year as new border restrictions were introduced and Mexico stepped up enforcement.

Mr Trump added: “Both Mexico and Canada have the absolute right and power to easily solve this long simmering problem. We hereby demand that they use this power… and until such time that they do, it is time for them to pay a very big price!”

After issuing his tariff threat, Mr Trump spoke with Canadian Prime Minister Justin Trudeau and they were said to have discussed trade and border security.

“It was a good discussion and they will stay in touch,” a Canadian source said.

Turning to China, the president-elect said he “had many talks with China about the massive amounts of drugs, in particular Fentanyl, being sent into the United States – But to no avail”.

“Until such time as they stop, we will be charging China an additional 10% Tariff, above any additional Tariffs, on all of their many products coming into the United States of America,” he wrote.

The Chinese Embassy in Washington said there would be losers on all sides if there is a trade war.

“China-US economic and trade cooperation is mutually beneficial in nature,” embassy spokesman Liu Pengyu posted on X. “No one will win a trade war or a tariff war.”

It is not clear if Mr Trump will actually go through with the threats.

He won the recent election in part due to voter frustration over inflation and high prices.

Mr Trump’s nominee for treasury secretary Scott Bessent – who if confirmed, would be one of a number of officials responsible for tariffs – has said previously that tariffs are a means of negotiation.

Conor McGregor has spoken out after losing a civil rape case as a feminist march was held in Dublin.

The MMA fighter was accused of raping Nikita Hand, who was awarded €248,603 (£206,000) in damages on Friday after a jury at Dublin’s High Court found McGregor assaulted her in a Dublin hotel in 2018.

Posting on social media, the 36-year-old said: “I know I made mistakes”.

It comes as hundreds of people in Dublin staged a demonstration in “utter solidarity” with Ms Hand.

Posting on X, McGregor said: “People want to hear from me, I needed time. I know I made mistakes. Six years ago, I should have never responded to her outreaches. I should have shut the party down. I should never have stepped out on the woman I love the most in the world. That’s all on me.

“As much as I regret it, everything that happened that night was consensual and all the witnesses present swore to that under oath. I have instructed my legal team to appeal the decision.

“I can’t go back and I will move forward. I am beyond grateful to my family, friends and supporters all over the world who have stayed by my side.

“That’s it. No more. Getting back to the gym- the fight game awaits!”

Speaking outside court after the decision, an emotional Ms Hand said the two-week-long civil case had been a “nightmare” but that “justice has been served”.

“It’s something that I’ll never forget for the rest of my life,” she added.

In Dublin on Monday night, a march in support of Ms Hand was organised by the socialist feminist movement group Rosa to mark the International Day for the Elimination of Violence against Women.

Participants chanted “stand with Nikita” and “no more fear, no more shaming, we reject your victim blaming” as they carried signs and banners through the capital’s streets.

Ruth Coppinger, a councillor and general election candidate, and Natasha O’Brien, who became a public figure after a soldier received a suspended sentence for assaulting her, both spoke at the event.

Ms Coppinger said Ms Hand was “an incredibly brave woman” and that she was watching the event via a live stream.

Ms O’Brien was cheered as she said she’d been “in awe” of Ms Hand’s courage and that Ireland had let out a collective “sigh of relief” after the jury found in Ms Hand’s favour.

McGregor was accused of having “brutally raped and battered” Ms Hand.

She was taken in an ambulance to the Rotunda Hospital the following day where the paramedic who assessed her told the court she had not seen “someone so bruised” in a long time.

Following eight days of evidence, and three days of closing speeches and the judge’s instructions to the jury, the jury of eight women and four men spent six hours and ten minutes deliberating before returning their verdict.

Two Britons are believed to be among more than a dozen people missing after a boat sank in the Red Sea off the Egyptian coast.

The yacht, called Sea Story, had 44 people on board, including 31 tourists of varying nationalities and 13 crew.

Authorities are searching for 16 people, including 12 foreign nationals and four Egyptians, the governor of the Red Sea region said, adding that 28 other people had been rescued.

Preliminary reports suggested a sudden large wave struck the vessel, capsizing it within about five minutes, governor Amr Hanafi said.

“Some passengers were in their cabins, which is why they were unable to escape,” he added in a statement.

The people who were rescued only suffered minor injuries such as bruises and scrapes with none needing hospital treatment.

A Foreign, Commonwealth and Development office spokesperson said: “We are providing consular support to a number of British nationals and their families following an incident in Egypt and are in contact with the local authorities.”

The foreign nationals aboard the 34-metre-long vessel, owned by an Egyptian national, included Americans, Belgians, British, Chinese, Finns, Germans, Irish, Poles, Slovakians, Spanish, and Swiss.

Sea Story had no technical problems, obtained all required permits before the trip, and was last checked for naval safety in March, according to officials.

The four-deck, wooden-hulled motor yacht was part of a multi-day diving trip when it went down near the coastal town of Marsa Alam following warnings about rough weather.

Officials said a distress call was received at 5.30am local time on Monday.

The boat had left Port Ghalib in Marsa Alam on Sunday and was scheduled to reach its destination of Hurghada Marina on 29 November.

Some survivors had been airlifted to safety on a helicopter, officials said.

The firm that operates the yacht, Dive Pro Liveaboard in Hurghada, said it has no information on the matter.

According to its maker’s website, the Sea Story was built in 2022.

The incident comes after the Egyptian Meteorological Authority issued a warning on Saturday about turbulence and high waves on the Red Sea.

The organisation had advised against maritime activity for Sunday and Monday.

Some tourist companies have stopped or limited operations on the Red Sea due to the potential dangers from conflicts in the region.
