The notions of an LEF group and of an LEF algebra, introduced by Gordon and Vershik in \cite{GV}, have been formulated in terms of local embeddability into finite groups or finite dimensional algebras, respectively. We will prove that the group algebra $\mC G$ of a group $G$ is LEF if and only if $G$ is. This solves a question raised in \cite{GV}.
