LondonIsOpen is a major campaign by The Mayor of London to show that London is united and open for business and to the world.

Since the campaign’s launch, Cavalier has worked alongside the Mayor of London’s office to deliver a series of high-profile videos, supported by famous Londoners, artists, musicians, and athletes. These films have garnered tens of millions of views and propelled #LondonIsOpen to be one of the most successful public sector communication campaigns of all time.
