German Chancellor Angela Merkel met with French President Nicolas Sarkozy in Berlin on Sunday in a mutual show of support ahead of European elections next month.  

Sarkozy's visit was the first time that a French president had campaigned in Germany in the run-up to an election. Merkel is scheduled to make a reciprocal trip to Paris at the end of this month, a diplomat said.

"We carry weight when we are united and when we know what to decide," Sarkozy said in Germany's Bild am Sonntag newspaper, adding that his relationship with Merkel was "efficient."

"She knows that she can rely on me like I know I can rely on her," he said.

However, Sarkozy also said his comments were not intended as an endorsement of support for Merkel in her bid to win re-election as chancellor in September. The French president insisted that was "for the Germans to decide."
