yes it has... no you cannot bring duty free back from Greece..why not you may ask, and i will tell, Greece is a member of the EU as is the UK therefore under EEC regulations you cannot transfer duty free goods between the two countries, you can however transport DUTY PAIED goods where you have a receipt to show you have payed duty in the country of purchase,
your allowance can be found on the government web site and if you choose to exceed the limits you must prove to the customs dept that such goods are for your personal use, the only one i know is 3,200 ciggies.
if you are thinking of booze then at the moment another overriding factor is in place that being the restrictions of taking liquids in to aircraft cabins and the other that alcohol is explosive and therefore cannot go in hold baggage

So a couple of bottles of spirits would be fine then. It's not a litre per adult...

the problem will be if they are still not allowing liquids on bard in your hand baggage, as i said earlier alcohol is not suppose to go in the hold as it is classed as flammable/explosive

Well I never knew that.... I have always wrapped mine up in my suitcase to protect it from breakage....
