Critics say passenger airliners, helicopters and pedestrians could have been endangered, after a music video was filmed by a drone above central London.

The video posted online showings aerial close ups of some of London's best known landmarks, has been condemned by professional drone pilots for being "dangerous".

They claim the filming violates a number of rules and regulations surrounding the safe use of unmanned devices in built-up and crowded areas.
