yesterday it was first day for mukul roy as railway minister and he was to give reply against discussion held on railway budget which was presented by trivedi. but mukul was not present in lok sabha. after opposition's uproar over absence of mukul, his deputy informed that mukul is in upper house for formal introduction by PM. after a while mukul came in lok sabha. then again mukul stood and left lok sabha. one MP from opposition asked ab wapas kaha ja rahe hai mantri ji, to which mukul said there's voting in rajya sabha so he's going to upper house. Hearing this Sumitra mahajan said " thik hai mantri ji chale jaiye, ana jana to laga hi rehta hai"
