Question: The Distribution of Industry act was passed by a man who was prime minister when? 

<P0-S0> The Reindeer Act or Reindeer Industry Act of 1937 is a United States federal law passed in 1937 by the U.S. Congress and signed into law by President Franklin D. Roosevelt on September 1 of that year. <P0-S1>  The act effectively prohibited the ownership of reindeer herds in Alaska by non-Native Americans. <P0-S2>  The act was intended to provide for Alaskan natives and to allow them to establish a self-sustaining industry. <P0-S3>  Authority to promulgate rules regarding the ownership and maintenance of reindeer herds was delegated to the Bureau of Indian Affairs via the Secretary of the Interior, who banned most transactions to non-natives. <P0-S4>  The act was modeled in part on Norwegian and Swedish policies on the ownership of reindeer by the Sami people of Lapland. <P0-S5>  Many Sami had arrived in Alaska to manage the reindeer in the 1930s. <P0-S6>  The Alaskan Sami were required to sell their herds to the government, and many left Alaska after doing so. <SEP> <P1-S0> Clement Richard Attlee, 1st Earl Attlee, {'1': ", '2': ", '3': ", '4': "} (3 January 1883 – 8 October 1967) was a British Labour politician who served as Prime Minister of the United Kingdom from 1945 to 1951 and Leader of the Labour Party from 1935 to 1955. <P1-S1>  In 1940, Attlee took Labour into the wartime coalition government and served under Winston Churchill, becoming the first person to hold the office of Deputy Prime Minister of the United Kingdom. <P1-S2>  He went on to lead the Labour Party to an unexpected landslide victory at the 1945 general election; forming the first Labour majority government, and a mandate to implement its postwar reforms. <P1-S3>  The 12.0% national swing from the Conservatives to Labour was unprecedented at that time and remains the largest ever achieved by any party at a general election in British electoral history. <P1-S4>  He was re-elected with a narrow majority at the 1950 general election. <P1-S5>  In the following year, Attlee called a snap general election, hoping to increase his parliamentary majority. <P1-S6>  However, he was narrowly defeated by the Conservatives under the leadership of Winston Churchill; despite winning the most votes of any political party in any general election in British political history until the Conservative Party's fourth consecutive victory in 1992. <P1-S7>  Attlee remains the longest-ever serving Leader of the Labour Party. <SEP> <P2-S0> The Distribution of Industry Act 1950 was an Act of Parliament passed in the United Kingdom by the Labour government of Clement Attlee. <P2-S1>  It strengthened the powers of the Board of Trade in the Development Areas, making “further provision for the acquisition of land, creation of easements and carrying out of work in development areas.” <P2-S2>  It also authorized “the Board of Trade “to make grants, in exceptional cases in connection with the establishment in, or transfer to, development areas of industrial undertakings, and to make grants or loans to housing associations for the provision of dwellings in development areas.” <P2-S3>  In addition, the Act also provided for payments towards the cost of removal and resettlement of key workers and their dependants. <SEP> <P3-S0> György Gordon Bajnai (] ; born 5 March 1968) is a Hungarian entrepreneur and economist, who served as the seventh Prime Minister of Hungary from 2009 to 2010. <P3-S1>  In March 2009, following Prime Minister Ferenc Gyurcsány's announced resignation, Bajnai was nominated by the ruling Hungarian Socialist Party (MSZP) to become Hungary's next prime minister. <P3-S2>  Bajnai became prime minister when the parliament passed a constructive motion of no-confidence against Ferenc Gyurcsány on 14 April 2009.
