Dr Singh was scheduled to visit Tokyo on November 15 for the India-Japan Annual Summit Meeting. The Summit meeting has been deferred due to the emerging political crisis in that country, informed the Spokesperson in the Indian External Affairs Ministry, Syed Akbaruddin.

According to sources it was Japan which wanted to defer the Summit Meeting.

The Japanese Prime Minister Yoshihiko Noda told Parliament on Wednesday he would agree to dissolve Parliament on November 16 and hold elections in December if the Opposition agreed to pass electoral system reforms.

After Noda made this announcement, yen fell sharply. The yen fell against the dollar and the euro as hedge funds and long-term investors such as reserve managers sold. The dollar rose 0.7 percent to 79.90 yen and the euro climbed 0.9 percent on the day to 101.75 yen.

Noda is Japan's sixth Prime Minister since 2006 and the third since his Democratic Party swept to power promising to change how Japan is governed after more than half a century of nearly non-stop Liberal Democratic Party rule.

According to political analysts, public support for the Democratic Party has plummeted due to policy confusion and political stalemate. Many in Noda’s party prefer to delay the election date.

The term of the lower house of the Japanese Parliament is scheduled to end in August 2013. According to sources Noda has been under growing pressure to cut it short since August when he promised Opposition parties to call 'soon' an election that his party looks certain to lose.

The pledge was the price for Opposition backing for his signature sales tax increase in the upper house where Opposition parties hold a majority.
