As of my most recent update in September 2021, the principal of East Durham College was titled and listed as Principal and Chief Executive. According to the government website, the salary range for the principal and chief executive of East Durham College for the year 2019-2020 was between £150,000 to £154,999.
However, please note that this information might be outdated, and the salary range may have changed since then. For the most up-to-date information on the principal's salary, I recommend visiting the official website of East Durham College or a relevant government database.
