Cruises: Wearing this item of clothing onboard could get you arrested

The UK government website warns: “It’s an offence for anyone, including children, to dress in camouflage clothing.”

A BBC report found that, in Grenada, convictions could be up to a year in jail or 10,00 East Caribbean dollars (£2,400).

Passengers should be aware of the local laws and customs when they make land, as they could break then without realising.

Cruise passengers can contact their cruise line or check the local government website.
