Meromorphic continuation and rationality of the abscissa of the zeta function follow as corollaries. If G is moreover a pro-p group, we prove that its representation zeta function is rational in p−s. These results were proved by Jaikin-Zapirain for p > 2 or for G uniform and pro-2, respectively. We give a new proof which avoids the Kirillov orbit method and works for all p.This paper is embargoed until publication.Journal Article10000-01-01
