Let Γ be a finite connected locally primitive Cayley graph of an abelian group.It is shown that one of the following holds:(1) Γ = Kn,Kn,n,Kn,n-nK2,Kn ×···× Kn;(2) Γ is the standard double cover of Kn ×···× Kn ;(3) Γ is a normal or a bi-normal Cayley graph of an elementary abelian or a meta-abelian 2-group.
Let Γ be a finite connected locally primitive Cayley graph of an abelian group.It is shown that one of the following holds：（1） Γ = Kn,Kn,n,Kn,n-nK2,Kn × · · · × Kn;（2） Γ is the standard double cover of Kn × · · · × Kn ;（3） Γ is a normal or a bi-normal Cayley graph of an elementary abelian or a meta-abelian 2-group.
