|Merged into||Liberal Party|
|Political position||Centre-right to right-wing|
The party was established in March 1947 as a merger of the Liberal Party, D?shi Club and a faction of the Democratic Party led by Sait? Takao. United by their opposition to the coal nationalisation law, the new party had 152 MPs and 46 members of the House of Councillors.
As a result of the DLP's attempts to block Yamazaki Takeshi from forming a new government after Hitoshi Ashida resigned as Prime Minister, the party's Shigeru Yoshida became Prime Minister in October 1948 and early elections were called in January 1949. The DLP won a landslide victory, taking 269 of the 466 seats, the first time a party had held a majority of seats since World War II. Shigeru Yoshida continued as Prime Minister.
