May 11, 2010 at 23:28 comment added BCnrd Giving $V$ its reduced analytic structure, the question is asking whether the local ring at $p$ is a complete intersection ring (due to general facts about Cohen-Macaulay and complete intersection rings; 17.4(iii)(3) and 21.2(ii) in Matsumura's "Commutative Ring Theory" book). It is equivalent to the completion of the local ring being a c.i. ring (21.2(i) in Matsumura). Thus, taking an reduced affine algebraic $\mathbf{C}$-scheme having a non-c.i. point gives (after analytification) a counterexample (by using excellence of analytic and algebraic local rings to track reducedness).
