The Gibraltar Parliament has 17 members, all elected for a four-year term in one constituency with each voter getting to vote for their selection of ten candidates.
People must be qualified to vote and listed on the Register of Electors in order to cast a ballot.
[2] British, European Union and qualifying Commonwealth citizens (those who had a permit or certificate to enter/remain in Gibraltar, or who did not require such a permit/certificate on the date of their electoral registration application) living in Gibraltar were entitled to register to vote in European Parliament elections if they were aged 18 or over on polling day.
For British nationals and Commonwealth citizens who moved abroad before they were 18 years old, they could still qualify for registration as an 'overseas elector' in elections to the European Parliament, with the 15 years period calculated from the date their parent(s)/guardian ceased to appear in the Register of Electors in Gibraltar.
Some people have advocated, including individual MPs, UKIP, the Liberal Democrats and the Gibraltar in Westminster Movement that Gibraltar should be extended the franchise of voting in UK general elections as a Westminster constituency.
