Airport; Airspace Structure; Procedure
I was working Final approach into Airport ZZZ landing ILS XX departing Runway YY. Airport ZZZ1 was departing Runway ZZ. Aircraft X was set up for right traffic to ILS Runway XX at 3;000. Aircraft Y VFR was pointed out at 4;500 feet. Normally VFR aircraft are sent under the Class Bravo airspace on this runway configuration at 2;500 feet. There was a controller change on the position working Aircraft Y; the new controller told Aircraft Y to descend out of the Bravo and proceed on course. Aircraft Y went on course and started a descent. His on course heading cut off the downwind Aircraft X was on; and the planes met at 3;000 and about 0.5 miles in the Class Bravo airspace. I called traffic and Aircraft X never reported Aircraft Y in sight. I was unaware at the time of what Aircraft Y was doing; I only saw him descending into my traffic.I suggest the VFR aircraft be kept outside of the Class BRAVO and also Airport ZZZ1 Class D be changed to a Class C and extended out to remove these VFR cut through flights away from Airport ZZZ and Airport ZZZ1 IFR traffic patterns.
Controller approved a point out of VFR traffic at 4;500 feet. The VFR aircraft was on a converging course with an aircraft at 3;000 feet being vectored for an ILS approach. The Controller working the VFR aircraft instructed it to descend and proceed on course. The descent put the VFR aircraft in to confliction with the 3;000 foot traffic.
