The Duke and Duchess of Cambridge will be joined by their two children on their eight-day tour of Canada later this month, Kensington Palace has said.

It will be the first official royal tour for Princess Charlotte, 16 months, and the second for Prince George, three, who accompanied his parents to Australia and New Zealand in 2014.

They stayed at home when their parents visited India and Bhutan in April.

Canadian Prime Minister Justin Trudeau invited the family to visit in July.

Mr Trudeau and his wife Sophie Gregoire Trudeau have three children - eight-year-old Xavier, seven-year-old Ella-Grace and two-year-old Hadrien.

'Great opportunity'

A Kensington Palace spokesman said: "They [The Duke and Duchess of Cambridge] have received so many wonderful messages from Canadians since the birth of their children and look forward to having the chance to introduce their young family to the country.

"This is a great opportunity to introduce their children to a major realm before things like school make this difficult later on."

The duke and duchess and their children will be based in Victoria - the capital of British Columbia - where the tour will begin on 24 September.

Kensington Palace is yet to announce when Charlotte and George will make an official appearance with their parents, but the first time the public will see the children is when they make their way down the steps of a Royal Canadian Air Force plane on arrival in Victoria.

During the trip the duke and duchess will go fishing on Haida Gwaii, an archipelago of some 450 islands off the British Columbia coast, when they visit members of the Skidegate Youth Centre.

The royal couple will visit British Colombia's Great Bear Rainforest, the world's largest temperate rainforest, and they will meet Syrian refugees at the Immigration Services Society of British Columbia in Vancouver.
