Tag former president jonathan at oxford university

I think there may be a slight issue here.

Former President Goodluck Jonathan of Nigeria is not a current student or faculty member at Oxford University. He is a former President of Nigeria, serving from 2010 to 2015, and has since returned to private life.

If you're looking to tag him for a specific purpose, I'm not aware of any official social media accounts or platforms where he is active. However, you may be able to find his official website or other online platforms where he may have shared his thoughts or opinions on various issues.

If you could provide more context or clarify what you're trying to achieve, I'd be happy to help!
