I am not sure M.Phil exists anymore, as the UGC doesn't approve of it, anymore. You have to go in for Ph.D. You may have to publish a couple of papers, before applying for Research. English Literature is offered all over India and there is no problem, on that count. The spade work must be completed, before finalizing admission in Ph.D. think of UGC NET also, first. The process is greater these days.
