This is really simple, if the other pilot has no medical, you are P1. As to instruction, if you are a FI or FIR, log it as instruction. As a FI(QFI) I always log any flight as instruction, if there is anyone else in the aircraft to keep the CAA happy, including my young children and mrs athonite, only exception is when in the past I have dropped parachutists, partly because there not there for the whole flight and the P2 seat is removed!
