Let u_0 be a uniformizer of O_K and let {u_n}_{n \\geq 0} be a sequence of elements of Q_p^alg such that P(u_{n+1}) = u_n for all n \\geq 0. Let K_infty be the field generated over K by all the u_n. If K_infty / K is a Galois extension, then it is abelian, and our main result is that it is generated by the torsion points of a relative Lubin-Tate group (a generalization of the usual Lubin-Tate groups).
