Premier Philippe Couillard is rearranging his international schedule to attend thenational  funeral of a Quebec celebrity.

The Premier will fly to Davos, Switzerland this week for the World Economic Forum, where the world's political and business elites meet.

The official theme of this year's meeting is "the fourth industrial revolution" -- the impact of robots on the worldwide economy.

However Couillard will cut short his trip in order to return to Montreal and attend Friday's national funeral for René Angelil.

Following the services, Couillard will return to Europe for the second leg of his economic mission, where he will meet company owners and trade officials in Milan, Italy.
