Valencia (Corts Valencianes constituency)
Voting is on the basis of universal suffrage, which comprises all nationals over eighteen, registered in the Valencian Community and in full enjoyment of their political rights. Amendments to the electoral law in 2011 required for Valencians abroad to apply for voting before being permitted to vote, a system known as "begged" or expat vote (). Seats are elected using the D'Hondt method and a closed list proportional representation, with a threshold of 5 percent of valid votes—which includes blank ballots—being applied regionally. Parties not reaching the threshold are not taken into consideration for seat distribution.
