In a previous work, we described the Minimal Model Program in the family of $Qbb$-Gorenstein projective horospherical varieties, by studying certain continuous changes of moment polytopes of polarized horospherical varieties. Here, we summarize the results of the previous work and we explain how to generalize them in order to describe the Log Minimal Model Program for pairs $(X,D)$ when $X$ is a projective horospherical variety.
