Justin Trudeau brings star power to White House

Canada's new prime minister, Justin Trudeau, is bringing his star power to the White House. He wants to strengthen a crucial alliance - the two countries have the longest common border and largest trading relationship in the world.

Mr Trudeau and President Barack Obama will be discussing new ideas for fighting climate change and expanding trade.

His visit is the first official one by a Canadian Prime Minister in nearly 20 years - the last one was Jean Chretien in 1997.
