"I can't understand why an aircraft on finals was required to go around because of following traffic. The student pilot, presumably being the lower aircraft, surely had right of way and the following traffic should have been told to go around."
At an airport with busy IFR traffic it can be hard to fit in VFR traffic between the jets. Sometimes I go for a gap with the VFR traffic then becoming No1, but on the understanding that if the IFR aircraft behind is catching up then the VFR ahead is sent around to hold north or south to wait for the next opportunity to land. This will not be done indefinitely and at some point a gap will be made for the VFR traffic but unless in emergency etc it will certainly not take priority.
I would sooner send a light aircraft around than a jet with 150 paying passengers!
