Talks to end a bitter student strike in Quebec have broken down according to the prime minister of the Canadian province.
The students are angry about plans to raise tuition fees by 75 per cent over the next seven years.
One hundred and fifty thousand have marched nightly in Montreal and Quebec City in protests that have sometimes turned violent over four months.
In just one night last week 700 people were arrested.
The students are also angry about a recent law aimed at making demonstrations more difficult to organise, saying it is unconstitutional.
Tourism officials are becoming increasingly unsettled about the image of Quebec that is being projected. Montreal hosts a major jazz festival later this month, and the Canadian Grand Prix is scheduled for 10 June.
