A bilateral agreement between Spain and the UK will allow the citizens of the two countries to continue to vote in local elections after Brexit becomes official on March 29.

The agreement will allow UK immigrants in Spain to vote in municipal elections due to be held in May in both Spain and the UK. Spain is home to a number of UK pensioners, tourism, and real estate professionals, some of whom are involved in local politics. Over 90,000 UK citizens are registered to vote in local elections in Spain.

As of April 2018, there were 37 elected British members of municipal governments in Spain.

Spain is the only country in the EU that is home to more British immigrants than it has sent overseas. There are over 300,000 UK permanent residents in Spain and only 175,000 Spanish citizens in the UK.
