Two police officers had their vehicles wheel clamped as they sat inside carrying out security duties for the Queen's recent visit to Portsmouth.
The two unmarked police vehicles were clamped during the royal visit to Gunwharf Quays on Wednesday for lunch aboard a luxury yacht.
Hampshire Constabulary said the clamping had prevented the officers from "conducting their duties".
Gareth Andrews, 37, from Fareham, has been charged with obstructing police.
mr Andrews, of Privett Road, is due to appear before South East Hampshire Magistrates' Court on 3 June.
The Queen's unannounced visit saw her have lunch on board the super yacht Leander, owned by NCP car park millionaire Sir Donald Gosling.
A police spokesman said: "The officers had not left the vehicles at the time they were clamped."
Mr Andrews is also charged with contravening the Private Security Industry Act, by not displaying the appropriate licensing badge.

Royal Protection will be armed with firearms... I'm guessing they were watching the wrong suspicious character. I think clampers are among the lower life forms so for one to boob this badly is excellent
