Turkish citizens living in Germany formed long queues to cast their votes in the upcoming referendum that will happen on April 16 for the constitutional amendment package.It has been reported that in Dusseldorf and Cologne, with high populations of Turkish voters, the queues exceeded 500 meters (1,640 feet), and some voters simply returned home to cast their votes at a later date.Speaking to Anadolu Agency (AA), Turkey's consul general in Dusseldorf, Şule Gürel, said 4,500 people cast their vote on Saturday alone and 10 ballot boxes were set up in the consulate over the weekend in order to meet the demand. She explained that the long queue was the result of the voters in front of the consulate building.Turkish people living in Germany can cast their votes until April 9 between 9 a.m. and 9 p.m. in Berlin, Cologne, Munich, Hamburg, Nürnberg, Karlsruhe, Frankfurt, Essen, Münster, Düsseldorf, Stuttgart and Mainz.Interest in the election remains high amid European interference favoring the "no" vote. On the first day of voting in the upcoming referendum for the constitutional amendment package, March 27, a total of 38,000 Turkish people living abroad cast their votes.The number is three times more than the first day of the Nov. 1 general elections, rising to 38,000 from 10,000. Information and data from prominent European countries that have a large Turkish diaspora, including Germany, Austria, Belgium, Denmark and Switzerland, have been gathered. Officials emphasized that participation in this election has been far greater than previous elections.
