Donald Trump has announced an immediate end to “all trade negotiations” with Canada over a television advert opposing US tariffs that quoted the former US president Ronald Reagan.

The advert, which was paid for by the government of the Canadian province of Ontario, uses excerpts of a 1987 speech where Reagan says “trade barriers hurt every American worker”.
