Dear Mr. Bain, you haven't mentioned the University you would like to seek admission in Ph.d in European Studies from. Pondicherry University has Ph.d in European Studies. We found this clause for your reference:

'Non-Resident Indians/Foreigners residing/working abroad and working in Academics/reasearch/industry at least for 10 years after acquiring the qualifying degree are exempted from appearing for the Entrance Examination. Instead, thry shall give a seminar either in person via video conference to the  Admission Committee. This committe will evaluate if the exemption can be made. NRI and Foreign Candidates with enormous professional experiences and proven research aptitude exhibited through publications will be considered under this clause'.

Going by this you should be exempted from appearing for the Entrance Examination. However, if you wish to, you can reach out to them at academictwo@gmail.com
