This paper reports that the authors study a Feigin-Fuchs construction of conformal field theories based on G {circle times} G/G coset space, in terms of screened bosons and parafermions. This allows us to get the formula for the conformal dimensions of primary operators. Lists of modular invariant partition functions for the SU(3), SO(5) and G{sub 2} Wess-Zumino-Witten models are given. Besides the principal series of diagonal invariants, a complementary series exist for SU(3) and SO(5), which is due to the outer automorphism of the Kac-Moody algebra. Moreover, exceptional solutions appear at levels 5, 9.21 for SU(3), at levels 3, 7, 12, for SO(5) and at levels 3,4 for G{sub 2}. From these modular invariants, those for the corresponding G{sub N} {circle times} G{sub L}/G{sub N + L} models are constructed.
