The Air Navigation (Restriction of Flying) (Anmer Hall) (Restricted Zone EG R220) Regulations 2015 were passed last week, and restrict air travel over the couple's Norfolk property, Anmer Hall.

"These regulations impose restrictions on flying in the vicinity of Anmer Hall, Norfolk," an explanatory note accompanying the regulations reads.
