We prove that there exists a universal constant D such that if p is a prime divisor of the index of the Fitting subgroup of a finite group G, then the number of conjugacy classes of G is at least Dp/ log2 p. We conjecture that we can take D =1 and prove that for solvable groups, we can take D = 1/3.
