The Different Than Majority Labelling (DTML) problem has a simple polynomial time sequential algorithm. The labelling given by this algorithm is called the Lexicographical First DTML. In this paper we show that the LF-DTML problem is P-complete. Furthermore, we show that even when restricted to planar graphs, the LF-DTML problem remains P-complete.
