[13] In keeping with IDS custom,[citation needed] the party leader holds the title of "coordinator".

[22][23][24] He was the founder[25] and previously served as leader of TRS,[26] but he stepped down[19] and subsequently also left the party prior to unification.

[25][27] Shortly after the 2018 parliamentary election, the party was also subject to criticism due to allegations by party technical staff of relatively low pay, burdensome workload, and poor work relations (particularly with parliamentary group secretary, Matej Kolenc).

Mesec, speaking about the affair, promised increased compensation for party staff, and voiced sympathy with the staffers regarding the hefty workload, explaining that due to high productivity of Levica parliamentary group relative to its small size, both MPs and political aides needed to overwork in order to accomplish as many political goals as they did during their first term.

[31] Nataša Sukič (who had hitherto served as the city councilor in Ljubljana)[32] was also elected on the party's ticket, becoming the first openly gay member of parliament in the nation's history.

[33] After the Christian conservative New Slovenia reneged on coalition talks with the five centre-left party core led by PM contender Marjan Šarec (leader of the eponymous election runner-up LMŠ party), The Left became the presumptive coalition partner in Šarec's efforts to attain a parliamentary majority.

[34] The Left's insistence on a NATO membership referendum was widely regarded as a deal-breaker for the more Atlanticist coalition core parties.

[36][37] Two days after Šarec was nominated for PM by the five-party group on August 8,[38] The Left vowed support for his candidacy.

[44] In October 2020, The Left joined center-left opposition parties in forming the Constitutional Arch Coalition (Slovene: Koalicija ustavnega loka - KUL), an initiative promoted by the Slovenian economist Jože P. Damijan aimed at forming an alternative government by uniting centre-left opposition parties.

It became clear in all this time, that The Left is formed out of a unique spectrum of red, and so it should continue, but the party should never forget its roots".
