With only a few months remaining until the next Lower House election must be called, the Liberal Democratic Party has postponed a plan to restrict so-called hereditary candidates until after the campaign, party sources said Tuesday.

The postponement comes amid speculation that Prime Minister Taro Aso may dissolve the Lower House in late June or early July and call a snap election in early or late August. The current term of Lower House members expires in September.

The LDP apparently failed to forge a consensus among its members, many of whom are from well-established political families. Such a rule would prevent their kin from inheriting not only their electoral districts but also their support groups and fundraising machines.
