Left gear collapsed upon landing. A part failed and allowed the gear to go up. I lowered the gear on downwind; all indicators showed gear down and locked. Upon touchdown; I slowly veered off the runway to the left. I immediately communicated my situation on the radio; still all indicators showed gear down and locked.
