Millions of German voters are casting their ballots to elect 99 out of 785 European MEPs – the largest contingent in Brussels.The Social Democrats wrapped up their campaign with German Chancellor Angela Merkel appearing at a rally in Heidelberg. She said she understood Germans were feeling alienated in Europe but she urged voters to go to the poll and vote. She said: “We need Europe to tackle the financial market regulation. We need Europe to deal with international claimate protection.” The Social Democrats, lead by Franz Muentefering, are expected to pick up twenty five per cent of the vote ..but observers say the European poll is seen very much as a dry run for Germany’s general election in September. Other parties on the ballot include the Free Democrats who insist Europe is good for peace. And the German Greens, a powerful voice with 13 MEPs, will make climate change and energy policy prominent in the campaign.
