Lewis Hamilton secured pole for the Monaco Grand Prix, putting the Mercedes star in the perfect position for victory on Sunday, but it was an embarrassing afternoon for rivals Ferrari.
The five-time world champion pipped Silver Arrows team-mate Valtteri Bottas to top spot, with Red Bull's Max Verstappen putting his car in third for the Monte Carlo showdown.
Ferrari's Sebastian Vettel suffered a late bump into the barriers in the final phase of the qualifying session, ruining any chances of putting his car on the front row for the race.
And, despite going fastest in final practice, Leclerc was dramatically knocked out of the opening phase of qualifying.
Ferrari appeared to think Leclerc's lap time was strong enough to survive Q1 but Vettel's late salvo bumped his team-mate out.
The Monegasque, who is now set to start 16th of the 20 runners, shook his head as he spoke to Ferrari mechanics in what appeared another miscalculation by the Italian team.
