Only around one in four Germans (26 percent) knows who Manfred Weber is, just a month ahead of a European election he hopes will help propel him to being the next European Commission president.

But Weber, the lead candidate for the European People's Party (EPP), is not alone in having a relatively low profile on the domestic political scene. According to a YouGov poll commissioned by dpa, 45 percent of Germans do not know any of the nine leading party candidates for the European Parliament election.

According to the survey, Katarina Barley, the Social Democratic Party's (SPD) lead candidate, is the best known of the leaders (39 percent), arguably because she has served as justice minister in the federal government.

Nicola Beer, general secretary of the Free Democratic Party (FDP) and candidate for the European ALDE group, is also known by only 26 percent of Germans.

Despite recent successes at a national level in Germany, the Greens' lead candidates for the European Parliament election are relative unknowns at home, with Ska Keller also scoring 7 percent and Sven Giegold 6 percent.

In the poll, 23 percent of respondents said they believe the European election is less meaningful than German federal, state and council elections.

The key issues for Germans for the May election are climate change and the environment (55 percent), and migration (54 percent).
