Miss Obama started at the Ivy League university this Autumn, following in the footsteps of her parents, who both attended Harvard Law.

Mr Farquharson began his studies at the university last year after completing his A-Levels, posting a picture of himself at the campus with the caption: "So it begins".

The 19-year-old, who attended the £11,584-a-term boarding school, was also a member of its chemistry club the Blue Bunsen Society.

Mr Farquharson was selected 'head of school' at the private school for the school year 2015 to 2016 and was described as popular and "quite a catch" according to one school friend.

He appears to be a talented sportsman as well as academically gifted, representing his school in both golf and rugby matches.

He even took part in a rugby video played at the World Cup Opening ceremony in 2015, in which Prince Harry also made an appearance.
