Following the death of his father, Bernard Kolélas, he succeeded him as Interim President of the Congolese Movement for Democracy and Integral Development (MCDDI), one of Congo-Brazzaville's main political parties, in 2010.
[3] During the 1997 civil war, Bernard Kolélas served briefly as Prime Minister before he and his old rival, President Pascal Lissouba, were ousted by rebel forces loyal to Denis Sassou Nguesso in October 1997.
On 7 December 1997, Kolélas sent his son to South Africa to acquire weapons that Lissouba had previously ordered from Ebar Management & Trading Ltd.,[4] a company that sold arms to the government during the civil war.
[8] The MCDDI, led by Bernard Kolélas, signed an electoral alliance with Sassou Nguesso's Congolese Labor Party (PCT) in April 2007.
[9][10][11] In the June 2007 parliamentary election, Brice Parfait Kolélas stood as the MCDDI candidate in Kinkala constituency, located in the Pool Region.
[12] The Pool Region was traditionally dominated by the MCDDI,[13] and Kolélas easily won the Kinkala seat in the first round, receiving 77.46% of the vote.
However, his father was by that point an elderly man in apparently declining health (although present, he failed to even give the closing speech at the convention), and thus Brice Parfait Kolélas was effectively being designated as the MCDDI's de facto leader.
[16] At the time of the July 2009 presidential election, Brice Parfait Kolélas was the Deputy National Director of President Sassou Nguesso's re-election campaign.
[18] Along with other major figures who had formerly opposed Sassou Nguesso, Kolélas was present for the launch of the campaign at a large rally held in Brazzaville in June 2009.
[19] After winning re-election, Sassou Nguesso promoted Kolélas to the post of Minister of the Civil Service and State Reform on 15 September 2009.
[29] On 1 February 2021, he was invested as a candidate for the presidential election on 17 and 21 March 2021 by his political party, the Union of Humanist Democrats-YUKI (UDH-YUKI).
