Now that the Diet session has been extended until July 28, the spotlight has shifted back to Prime Minister Taro Aso as politicians and analysts try to predict when he will dissolve the Lower House and call a snap election.

Political insiders and commentators speculate that Aso, seeking a ratings boost by appearing on the global stage, will not dissolve the house before the July 8-10 Group of Eight summit in Italy. The Tokyo Metropolitan Assembly election on July 12 will probably provide enough reason for a further delay.

Some analysts say the general election, which must be called by September, could be held as early as Aug. 2, while others think Aso may try to push it back to the end of August or early September. A mid-August race seems unlikely because it would conflict with the Bon holiday.
