This is not the first time Bertie has achieved academic success, as Morgan previously revealed in 2019 that his son had obtained three A* grades.

Morgan also took the opportunity to praise Wellington College in Berkshire, where Bertie received his education.

At the time, Morgan said: "Congrats No3 ⁦‪@bertie_morgan‬⁩ on your 3 A*s. The apple fell in a different orchard to your old man (I only got ABC)… "Proud of you son, due reward for tremendous work ethic. And thanks to ⁦‪@wellingtoncollege‬⁩ for giving him a superb education. #alevels2019".

Bertie is the youngest of Morgan's three children with his ex-wife, Marion Shalloe.

Morgan also has two older sons, Spencer and Stanley, as well as an 11-year-old daughter named Elise with his second wife, Celia Walden.
