The dinner at Tuesday's high table might not prove to be sumptuous enough to bring Samajwadi Party (SP) president Mulayam Singh Yadav to the UPA fold. A day after the much-hyped event in Delhi marked three years of UPA-II, SP general secretary and Rajya Sabha member Ram Gopal Yadav ruled out his cousin Mulayam joining the Manmohan Singh government. "There is no question of his joining the UPA government. We have attended dinners in the past also, as we are extending outside support to the UPA."
