Canada’s ruling Liberal party lost a once-safe seat in a Montreal parliamentary constituency, preliminary results showed on Tuesday, a result likely to put more pressure on Prime Minister Justin Trudeau to quit. Elections Canada said that with 100 per cent of the votes counted in LaSalle-Emard-Verdun, Liberal candidate Laura Palestini had been beaten into second place by the separatist Bloc Quebecois candidate, Louis-Philippe Sauve.
