[Definitions: The Soclesocle of a group (is$G$ is the subgroup generated by the minimal normal subgroups of $G$) of abelian $p$-group of infinite rank has infinite rank.

The socle of an abelian $p$-group of infinite rank has infinite rank. I wonder if it is true in the locally nilpotent case.:
Is the following assertion true: Let $G$ be locally nilpotent $p$-group. If $G$ has infinite rank, then the socle of G i.e $SOC$($G$) has infinite rank.
