A giant blimp of Sadiq Khan could fly over London after mayor approves a Donald Trump one to fly during his visit

A giant blimp of Sadiq Khan could fly over London after mayor approves a Donald Trump one to fly during his visit: A CROWD-FUNDING page smashed its target to fund the stunt after the London Mayor approved plans for anti-Trump demonstrators to fly their own blimp during the US President's visit. The only way this plan can be stopped is if Mr Khan blocks it.
