azzie - You cannot now obtain a UK licence, only a JAA one.
The JAA are currently in discussion with the FAA about this very matter but don't hold your breath. Even if they can agree on reciprocity, the most optimistic target is 2 years before anything is in place. As far as I am aware negotiations are not in progress with any other non-JAA country.
Meanwhile there is no mechanism for conversion of non-JAA licences, you will have to take all ground exams as well as the CPL and IR Skill Tests. Previous experience may allow a reduction in training hours but no other benefit.
In the case of the holder of an ICAO ATPL with in excess of 500 hours experience in multi-crew operations, there is an exemption from the IR and CPL Skill Tests. However, all 14 ground exams must be passed as must the ATP(A) Skill Test which must be taken on an aircraft certified for multi-crew operations.
BIK_116.8 - The UK CAA have no discretion in this matter, the rules are laid down by the JAA where the UK is in a minority of one. Blame would be more appropriately laid at the door of the French DGAC who, supported by one or two other southern european authorities, are railroading through their own protectionist agenda. As to the attitude of 'some UK pilots', you get a proportion of dickheads in any profession.
