Clean and tidy, polite, quiet and uncomplaining, Japanese tourists came top of the crop for the third year running.

At the other end of the spectrum, French holidaymakers and business travellers were the least generous or ready to tip, and ranked next-to-last for their overall behaviour and politeness.

Pushy French travellers made amends on elegance — classed third — as well as for their discretion and cleanliness.

But the French were the least ready to try a new language, unlike US tourists who were most likely to swallow their pride and order a pizza, baguette or a paella in the local lingo.
