The Liberal Democratic Party on Tuesday backed down from its crusade to block a package of bills on postal services deregulation, saying it would approve the legislation's submission to the Diet.

Key LDP panels declined to fully endorse the contents of the bills, however, and vowed to take countermeasures via debate within the party and the legislature.

The decision marks the first time that the LDP has decided to allow the government to submit legislation to the Diet before approving its contents. LDP policy decisions are traditionally made by Policy Research Council divisions and approved by the Executive Council before Cabinet endorsement is sought.
