•  Donald Trump says he will introduce 25% tariffs on goods coming from Canada and Mexico on day one of his presidency.
    • He also vows to add an extra 10% on goods coming from China - imports from there to the US are already subject to some tariffs.

    • For context: A tariff is a tax paid on goods as they enter a country. The company importing the goods pays the tax, not the foreign company that exports them.

    • Trump's announcement comes about two months before he takes office, with BBC's North America correspondent Anthony Zurcher writing there may be room for negotiations .

    • China calls the tariffs "irresponsible" and warns that no-one will win a trade war.

    • Mexico's president also warned it could retaliate with its own tariffs if Trump's plan goes ahead.
    • Doug Ford - leader of Canada's most populous province, Ontario - says a 25% tariff would be "devastating to workers and jobs"

Tom Homan - Trump's appointed 'border tsar' - is heading to Texas on Tuesday to meet with the state's governor and inspect conditions along the US-Mexico border.

Trump made illegal immigration a major focus of his campaign, describing southern border crossings from Mexico as an "invasion of illegal aliens". He has vowed to swiftly end it, including using the US military to help with mass deportations.

After he won the election in November, he quickly began assembling his transition team and Homan, who worked in Trump's first administration to enforce immigration laws, was one of his first picks.

Trump has said he would enact the "largest deportation operation" in US history on his first day in office and has tapped Homan to lead that effort.
