According to the Code of Good Practice in Electoral Matters, the right to vote may be accorded also to citizens residing abroad. There are good reasons to do so (see CDL-AD (2011) 022), and, in fact, most CoE member states have since introduced legal provisions for out-of-country voting. Recent examples include Hungary (2014), Romania (2015) and Greece (2019). In a few European countries that allow external voting, voting rights are removed from those citizens who live abroad for a long period of time, namely, in the UK after more than 15 years and in Germany after more than 25 years (with some exceptions). In some other countries, citizens no longer registered as residents are still included in electoral rolls for a certain period of time (for instance, ten years in Sweden). Thereafter, they must actively register from abroad.
