Photos: Saudi Crown Prince on a 3-day trip to the UK & adverts welcoming him pop up in London

Saudi Arabia’s Crown Prince Mohammed bin Salman is beginning a three-day visit to the UK and people have noticed a lot of promotional adverts appearing in the papers, on black cabs, roadside billboards and vans.

The Crown Prince will meet with the heads of MI5 & MI6 and he has been invited to sit in on a meeting of the National Security Council, a rare event for a Foreign Head.
