Abstract. Assuming the Generalized Riemann Hypothesis (GRH), we show using the asymptotic large sieve that 91% of the zeros of primitive Dirichlet L-functions are simple. This improves on earlier work of Ozluk which gives a proportion of at most 86%. We further compute q-analogue of the Pair Correlation Function F (α) averaged over all primitive Dirichlet L-functions in the range |α| < 2 . Previously such a result was available only when the average included all the characters χ. As a corollary of our results, we obtain an asymptotic formula for a sum over characters similar to the one encountered in the Barban-Davenport-Halberstam Theorem.
