Finnish Government and the President tilted heavily towards the President. In principle and formally, parliamentarism was followed with governments nominated by a parliamentary majority. However, Kekkonen-era cabinets were often in bitter internal disagreement and alliances formed broke down easily. New cabinets often tried to reverse their predecessors' policies. Kekkonen used his power extensively to nominate ministers and to compel the legislature's acceptance of new cabinets. Publicly and with impunity, he also used the old boy network to bypass the government and communicate directly with high officials. Only when Kekkonen's term ended did governments remain stable throughout the entire period between elections. Nevertheless, during Kekkonen's presidency, a few parties were represented in most governments — mainly the Centrists, Social Democrats, and Swedish People's Party — while the People's Democrats and Communists were often in government from 1966 onwards. Throughout his time as president, Kekkonen did his best to keep political adversaries in check. The Centre Party's rival National Coalition Party was kept in opposition for 20 years despite good election performances. The Rural Party (which had broken away from the Centre Party) was treated similarly. On a few occasions, parliament was dissolved for no other reason than that its political composition did not please Kekkonen. Despite his career in the Centre Party, his relation to the party was often difficult. There was a so-called K-linja ("K policy", named after Urho Kekkonen, Ahti Karjalainen and Arvo Korsimo), which promoted friendly relations and bilateral trade with the Soviet Union. Kekkonen consolidated his power within the party by placing supporters of the K-linja in leading roles. Various Centre Party members to whose prominence Kekkonen objected often found themselves sidelined, as Kekkonen negotiated directly with the lower level. Chairman of the Centre Party, Johannes Virolainen, was threatened by Kekkonen with the dissolution of parliament when Kekkonen wanted to nominate SDP's Sorsa instead of Virolainen as Prime Minister. Kekkonen's so-called "Mill Letters" were a continuous stream of directives to high officials, politicians, and journalists. Yet Kekkonen by no means always used coercive measures. Some prominent politicians, most notably Tuure Junnila (NCP) and Veikko Vennamo (Rural Party), were able to brand themselves as "anti-Kekkonen" without automatically suffering his displeasure as a consequence. First term (1956–62) In the presidential election of 1956, Kekkonen defeated the Social Democrat Karl-August Fagerholm 151–149 in the electoral college vote. The campaign was notably vicious, with many personal attacks against several candidates, especially
