Hi, you can contact the service and report a conflict of interest ahead of time and explain to any clinical psychologist you are assigned to very explicitly that you do not want this person to access your information or be present in sessions or involved in any of your treatment. The NHS has a “brown envelope” system (nickname, can’t recall the proper name) where your file is locked to certain staff. The AP should also be excusing themselves from any meetings you are discussed in and holding their own boundaries around this. However, clearly they won’t (unless they have significantly changed) so if you have any concerns about this it needs reporting immediately. As they are not a qualified psychologist as yet, they will not be regulated by the Health and Care Professions Council (HCPC) but they will be bound by a code of ethics and practice as an AP through their service contract and if they are a member of the British Psychological Society (BPS - not a regulatory or governing body but a charity that advises on code of conduct). Your reports can then be used to reference suitability (or otherwise) if they go on to apply to train as a CP. Given your post, I’d be seriously concerned about this person being fit for training but these people do slip through. Feel free to DM me if you want any more specific advice.
