On ILS to XXR we were instructed to maintain visual separation with the aircraft in front of us on ILS to XXL. He blew through his localizer and ours. We slowed to avoid. He reported responding to an RA. He corrected back to the south and went into a cloud deck. We reported loss of visual with him and were told to go around by ATC.
Approaching ZZZ on the ZZZZZ [arrival]; cleared for ILS XXL approach. A 737 was on a long final visual approach to XXR. I do not know how a visual is assigned when visibility and ceiling are low. Our intercept angle was published at about 45 degrees; and with a tail wind; on autopilot; our aircraft overshot the LOC a bit. The most that we saw was one dot deflection. Just then we got an RA; so I turned off autopilot; descended as instructed and flew the command bars to stay on the LOC. The aircraft on XXR did a go around.
Two B737 flight crews reported that a localizer overshoot and cloudy conditions resulted in the inability to maintain visual separation.
