OTTAWA – Canadian Prime Minister Justin Trudeau is under investigation for a holiday he took on a private island belonging to billionaire spiritual leader of Ismaili Muslims, Prince Aga Khan at the New Year, the Independent reported.

Canada’s federal conflict-of-interest and ethics office said it was investigating whether the visit to the island broke rules preventing ministers from accepting bribes.

PM Trudeau said he was “more than happy” to answer the commissioner’s questions.

The island is owned by Prince Shah Karim Al Hussaini Aga Khan – leader to the world’s 15 million Ismaili Muslims, a denomination of Shia Islam.

The 71-year-old is a close family friend of the Canadian Prime Minister and was an honorary pallbearer at the funeral of Mr Trudeau’s father, Pierre.

He chairs a development network, which promotes investment in Asia and Africa, and is considered the world’s 11th richest royal – just ahead of the Queen.

Trudeau was accompanied on the trip to the billionaire’s island by his family and two fellow Liberal politicians: MP Seamus O’Reagan and Party President Anna Gainey.
