Justin Trudeau wore a pair of green trainers for the King’s speech at the state opening of Canada’s parliament in Ottawa.

The former Canadian prime minister chaperoned his mother, Margaret, into the Senate chamber for the historic speech, while dressed in a navy suit and a pair of the turquoise and orange Adidas Gazelles.

The King used his speech to impress on Canadians their country is “strong and free” following Donald Trump’s recent threats to make it America’s “51st state”.

Mr Trudeau had a prominent seat during the speech, meaning his footwear may have been visible to the visiting royals.

Critics mocked Mr Trudeau’s choice of footwear on social media.

Dimitris Soudas, who was the communications director for former Conservative Party prime minister Stephen Harper, shared a photo of Mr Trudeau’s outfit, captioned: “I don’t know what to say.”
