He led the Socialist People's Party electoral list in the Podgorica local election of May 2014 under the slogan "youth, wisdom and courage".[6] In 2015 he became one of the founders of the Democratic Montenegro Party, when the faction of the Socialist People's Party of Montenegro defected from the political party, and formed new political subject, represented by 2 MPs in the Parliament of Montenegro.[7] A newly formed party ran independently at the 2016 parliamentary election under the slogan "Victories, not divisions",[8] increased their number of MPs from 2 to 9 and becoming one of main opposition parties in Montenegrin Parliament. Since the constitution the new parliament the entire opposition (all 39 MPs out of 81 in total) started a collective boycott of all parliamentary sittings, due to claims of electoral fraud at the 2016 parliamentary elections, Bečić along the other Democratic Montenegro MPs remained in a boycott with the same demands until the end of the term.
On 5 October 2020, Bečić, along with the European Union Ambassador to Montenegro Oriana Christina Popa opened the new War Crimes Documentation Centre in the capital Podgorica, stressing that the country must face up to its wartime past.[11]
In 2018, Bečić faced intense public scrutiny, as a research study conducted by NGO Center for Public Integrity accused him of plagiarising significant portions of his Master thesis from various online sources.[13] Bečić had repeatedly denied these allegations,[14] calling it a coordinated smear campaign jointly conducted by parts of the DF and the ruling DPS.[15]
Bečić never stated how he declares himself by ethnicity, and when he was asked what language he speaks in the show Questionnaire on RTS, he said: "Hey, in Montenegro ... let me tell you, I did not come here today as a citizen of Montenegro. Today, I am the president of a political party that brings together people of all faiths and nations and that has managed to bring together and reconcile people who were divided in the previous period and who had different ideological determinants.”[17] He finally stated in a parliamentary session in 2022 that he is Montenegrin and speaks Serbian.[18]
For a long time, he did not say whether he supported the Serbian OrthodoxMetropolitanate of Montenegro and the Littoral or the Montenegrin Orthodox Church.[citation needed] However, at the end of 2019, he opposed the controversial Law on Freedom of Religion and participated in the religious protests organized by the Metropolitanate, stating that the law must be in accordance with all three traditional denominations, also accusing the ruling party of inciting ethnic hatred and unrest.[19][20] At the time of Montenegro's recognition of Kosovo's independence in 2008, he expressed "a form of dissatisfaction with the circumstances surrounding the decision", while in 2017 he said he did not want to regulate "Serbia-Kosovo interstate relations" and that the question of Kosovo's independence should be to let young people out of the clutches of Balkan primitivism ".[17]
