was appointed Chairman of the National Security Committee on 28 June 1994. He also became Vice Chairman of the Committee for Financial Support for Public Organizations on 27 December 1994, holding this position until 11 December 1995. During the campaign for the 1996 party leadership election, Boross supported Sándor Lezsák who ran as candidate along with the more liberal and urbanist Iván Szabó, who was more acceptable for the party elite and the former government members. At the end of 1995, Boross resigned as vice-president of the MDF because he disagreed with the policy of the party leadership chaired by Lajos Für. In March 1996, Lezsák was elected President of the Hungarian Democratic Forum, as a result Szabó and most of the governmental figures of the Antall period, including 15 MPs left the party and founded the Hungarian Democratic People's Party (MDNP). Boross resigned as Chairman of the National Security Committee following that, but remained a member of the MDF. He worked in the Committee for Constitutional Preparatory and Committee of Economics since April 1994 until end of the parliamentary term in June 1998. Boross lost his parliamentary seat in the 1998 parliamentary election. Boross served as political advisor to Prime Minister Viktor Orbán, whose party the Fidesz won the 1998 election and the MDF also involved in the government as a coalition partner. Since then Boross was long considered a supporter of Minister of Justice Ibolya Dávid, who became leader of the MDF in January 1999, replacing Sándor Lezsák. Boross did not run again for the position of party vice-president during the election of officials. His relationship with Orbán became conflictual by early 2001, even after replacement of ministers Attila Chikán and József Hámori. Boross also criticized the Orbán cabinet's economic policy and its biennial budget. In 2003, Boross left the MDF's national board. He was elected President of the National Memorial and Tribute Committee in 2006, replacing Anna Jókai who had held the position since 1999. He was elected as a Member of Parliament from his party's Pest County Regional List during the 2006 parliamentary election. Before the election's second round, Boross argued the left-liberal MSZP–SZDSZ governing coalition's advantage is unbeatable, therefore he received numerous criticism from the right-wing intellectuals. He became a member of the National Security Committee following the election. In the upcoming years the MDF gradually shifted to the left-wing under the leadership of Ibolya
