Prince Harry has reportedly promised grandfather Prince Philip that he’s going to leave his partying ways behind.

The prince, who is third in line to the throne, has been a regular on the London party scene in between his army assignments, most frequently at South Kensington club Boujis.

A Royal source told the Mail on Sunday: “Harry will probably go out to let off some steam now he’s back home but he has said his Boujis nights are numbered.

“He and his grandfather are very close and Harry is determined that Prince Philip knows how seriously he takes his role.

“Harry has said he is busy planning the next step of his military career and wants to continue doing charity work in Africa.

“Philip sees a lot of himself in Harry. He loves his get-up-and-go, his love of the Army and his sense of humour.

“He wants to know that Harry is going to be a dutiful Prince, not a wayward one.”
