I am planning a trip to Italy in January of 2012. I am just wondering if I will be allowed to enter the country as my UK passport has less than 6 months remaining until it is due to be renewed.
Just leave before it expires.
The Italian embassy in London says this:
1.2 UK Passport validity for travelling to Italy Foreigners may travel to Italy provided their UK passport is valid when they exit Italy (no minimum validity required). This applies to all EU passport-holders. If you have a non EU passport, please consult the website of the Italian Foreign Ministry to verify whether you need a visa to enter Italy
From the Lonely Planet visa site for UK citizens visiting Italy:
All travelers will need a passport valid for at least 90 days following your departure date from Italy. However, we strongly recommend traveling with 6 months validity on your passport at all times. Citizens of United Kingdom can refer to www.ips.gov.uk for forms and instructions for new passport applications and British passport renewals.
