Can you work in Italy as a british passport holder?

Yes, as a British passport holder, you can work in Italy, but you will need to comply with the post-Brexit Immigration regulations. Since the end of the Brexit transition period, UK citizens are subject to the same rules as non-EU citizens, which may involve securing a work visa or permit prior to employment. It's important to check the specific requirements based on your situation, such as the type of job and duration of stay.
