US President Donald Trump has said he is serious about wanting Canada to become the 51st state in an interview that aired during the Super Bowl pre-show.

“Yeah it is,” Mr Trump told Fox News Channel’s Bret Baier when asked whether his talk of annexing Canada is “a real thing” – as Canadian Prime Minister Justin Trudeau recently suggested.
