Trivandrum: Muralidharan said he is returning to the ‘I’ Group in the renewed atmosphere of High Command giving it a tacit approval. Ramesh and me are of the same mental attitude and I have no ego to settle with Ramesh. I solemnly approve Ramesh as the leader of the ‘I’ Group. There is no existence in congress without a group. So I’m again becoming a part of my old parent group, said Muralidharan. This decision was taken in a meeting held at Kozhikkode.
