Having completed my MPhil, I was wondering if it was possible to extend it to PhD. I understand this raises questions, which would be difficult to answer. The circumstances in terms of the awarding institution were difficult and complex. It took far too long to complete the MPhil but, despite untenable circumstances, I was determined to complete. I hesitate to give details, despite the anonymity offered by this forum, because I do not wish to publicly call the reputation of the institution into question over one department. Suffice it to say, answering prospective supervisors' questions over the time taken would put me in a difficult position, especially as I also work in the institution and therefore have loyalty towards it, just as many colleagues have offered their support to me.

This can be problematic as there are rules about not submitting the same work twice for different qualifications in the same institution. But it's not clear from your post whether this is what you want to do or whether you're trying to go elsewhere. I think you'd have to be up front with any potential supervisor about the circumstances though, as otherwise if you did take a long time over it, they will assume that this is a failed PhD that was awarded an MPhil as an outcome, and then I think they'd be very unlikely to agree.

Many thanks. That is much as I thought. However, after my experiences and following colleagues' advice, I would certainly be looking elsewhere. fyi (this is too important to me, so I've decided to give more information) there was a great deal of difficulty finding qualified examiners. I had applied for an MPhil originally (various reasons), but was encouraged to apply for a PhD in the first year by the head of research on the strength of my work and presentation of the study on the compulsory Social Research Methods course. However, it was rejected as not being original. The examiners who were found were knowledgeable but unqualified to examine because it was original - as acknowledged by my second supervisor (see below) and encompasses several specialist fields An experienced examiner in one related field was present as 'quality control'. They described the thesis as "truly original research" and were encouragingly complimentary. During the study, my supervisor - who had no real knowledge or experience in my field - left the institution and essentially 'disappeared'. It was no surprise that my new supervisor advised me to dispense with what I had done and essentially start again. Indeed, it was a relief - somewhat ironically, it ended up as intended from the start. Now I have confirmation of its originality and quality, I would dearly love to take it further.
