Berlin hails Iran vote for 'constructive foreign policy'

German Foreign Minister Guido Westerwelle on Saturday welcomed the election of moderate cleric Hassan Rowhani as Iran's new president as a vote for reforms and "a constructive foreign policy".

"We hope that the country's new administration collaborates in this sense in order to reach solutions on international and regional questions," Westerwelle said in a statement

Rowhani, 64, was declared Iran's new president, ending eight years of conservative grip on the top office in a victory cheered in the streets of Tehran and cautiously welcomed by world powers.

Iran's contentious nuclear programme has caused a standoff with the West, which suspects it is aimed at building nuclear weapons something Tehran has repeatedly denied.
