More or less inexistent. The Lebanese Communist Party has no more popularity even after it rebranded itself as soccdem in the 70's.
The Progressive Socialist Party adopted sectarian politics after the assassination of its former leader.
There is the Communists Action Organisation in Lebanon which still upholds its socialist character.
After the 17 october 2019 protests, a new grassroot party emerged called "Citizens in a State" whose leader is an approved communist. But the party's constituents are diverse, from liberals to socdems, neoliberals, socialists and so forth. Wasn't very fond of their programme.
I think the main issue of the political left is its failure to attract and mobilize the working class. The only recent example I can recall is the establishment of a labor union by the workers of Spinneys (supermarket chain) after intense legal battles with the help of the communist leader that I mentioned earlier.
