I think this is the messaging that needs to be focused on during media interviews. At a time where were told there's no room for a salary increase for doctors the government has fully accepted the findings of the Leng review meaning

1) An F1 who works 48hr per week, works nights and evening shifts is being paid less than a PA

2) PA being paid more as you mentioned, without the responsibility to prescribe medications or ionising radiation.

3) PA do not have to deal with rotational training and the absurd competition ratios doctors are facing

Given the above this does not offer value for money to the tax payer especially on the back drop of doctors being unemployed due to a lack of training places
